DNA Results

We recently asked that any of you who have submitted DNA to a testing service share the results with us. By sharing we mean that we are asking for the list of potential matches that your service reports. In most cases this can be well over 1,000 names. Names are designated a potential relationship type such as 1st Cousin, 2nd Cousin and so on. But don’t be surprised to see a potential 2nd Cousin name that is totally unknown to be related. On the same hand a 4th or 5th Cousin name could be one that is known in fact to be related.

We have lists from Anthony DePollo and Joseph J. DePollo showing links to newly discovered relationships to Feliciano DiPaolo and several of his descendants. Among those descendants are John Holt, Kenneth Powell, Shirley Holt, Zack Holt and Mary Holt Wilson. Anthony’s DNA relatives report include John Holt, Jeanne Waite Follett, Kenneth Powell, Marc D’Alosio and Harrison Coleman. Many other names that are the same are in both their potential DNA Relatives reports.

In case you didn’t realize it the various services do not share their results with one another. Therefore, for example, if you submitted to ‘23andMe‘ and another potential relative submitted to ‘AncestryDNA‘ the two of you will not show up in the DNA report for one another. This is the basis of our request to get copies of the potential match lists that all of you might have. We can compare the lists and see if we discover matches that individually might be missed. Don’t presume that if you submitted to the same service as another that the list will be the same for both in entirety.

For some of you the problem is knowing how to download the list of potential matches in your report. If you use ‘23andMe‘ it’s simple to get a copy of the list in a format that can be opened with Microsoft Excel.
The download option for the results list of potential matches is found under a tab identified as DNA Relatives, which is under the tab Family & Friends. The download link is found near the bottom of the page. The downloaded file is in CSV (Comma Seperated Values) format and can be opened with Excel.

For those who submitted to ‘AncestryDNA‘ there is no simple method on the AncestryDNA report pages to allow you to download the list of names. However, using the ‘Google Chrome‘ browser you can install a ‘Chrome Extension‘ that is specifically designed to download the list. Do a search on Google for ‘AncestryDNA Helper‘. If you do not have the ‘Chrome’ browser installed you will need to do so in order to use the ‘AncestryDNA Helper‘. Note that you can have multiple browsers installed with no issue. You may find that you actually prefer to use Chrome. If you have an Android phone you will already be familiar with Chrome.

Once you have AncestryDNA Helper added to Chrome you will be able to download and save a list of the potential DNA relatives as an Excel file.

Other DNA services may have their own method of allowing you to download a potential DNA Relatives list.

DNA Test Results

We’re still hoping that those who have had a DNA test will share their results with us. There’s information that you may be overlooking! Most people browse through their online report looking for names they recognize. There is a lot more to analysis than simply locating familiar names. Give us help in expanding the analysis. So far we only have the results from one person’s 23andMe DNA test.

There are a number of DNA testing services and they do not share data with one another. One thing they do though is to sell test results to big pharmaceutical companies. We’re not sure that is a good thing!

Anyway, the results are constantly updated as new DNA submissions are made. That’s the reason they don’t mail reports to you. However with most services you should be able download a file that has the data that is currently available.

If you had a DNA test through Ancestry DNA here’s a link to instructions on how to download the raw data to a file that you could share with us. Click here for the instructions!

If you used 23andMe DNA testing you would use the Quick Links on the Home page to go to the section titled DNA Relatives. At the bottom of the page is a link that says ‘Download Aggregate Data’. Click that link and a text file will download with the listing of all the names that may have common DNA markers to you.

Other DNA services most likely have the same options to download data.

If you can send us a copy of the file you download it will help us to see if there are any names you overlooked, or names that are unfamiliar to you, that may be potential family connections.

If you are willing to participate please send your file download as an email attachment to info@depollofamily.com

Did you DNA Test?

We would like to hear from anyone who has had a DNA test. There are many different testing services available. The results can vary slightly between the different testing services.

For those seeking to discover genealogical relationships DNA testing is a “tool” for part of their research, but is not a source for hard facts. You need to piece it together with all the research and documented support, family history handed from parent to child and various official records.

All DNA testing is not linked

Unfortunately it seems that if you’ve taken a DNA test from one service it is not shared with results in another service. So, that a problem when you test with Ancestry DNA and other persons known to be related to you take a DNA test with 23&Me. Neither of you will show the other in the results each of you receive from your service. By testing with multiple DNA services you might see previously unknown relationships as well as known ones. In other words you’d have to do your own ‘sharing’ of results. Multiple tests means greater cost so it’s unlikely that most people will do a DNA test with several different companies. We would like to ‘compare’ and link results by seeing the results that family members have gotten from any DNA test they’ve taken.

Some thing to consider. . .

The executive director at the Center for Genetics and Society, said “When you provide your genetic information to a DNA testing company, you are also providing information about those related to you — including distant cousins. When your relatives, including distant ones whom you may not even know, provide their DNA, they are also providing genetic information about you.”

It was also noted that while testing companies stress that DNA data is “de-identified” to protect privacy, data shared with researchers can be re-identified in many cases. DNA testing therefore might connect someone to a crime scene, a domestic issue or an accident. Law enforcement would be one example of requests to use DNA from a testing company without the consent of the submitter, and re-identify it. Its already been done recently!

NOT THAT HARD TO IDENTIFY YOU

A 2008 law called the Genetic Information Nondiscrimination Act forbids discrimination based on genetic information and that would include firing someone because they have a gene that predisposes to an expensive disease. But it would also be hard to prove an employer did that!

DNA testing provides an ‘educated’ assumption of relationships.

Haplogroup is the term scientists use to describe a group of Y-chromosome (or mitochondrial) sequences that are more closely related to one another than to others. One of the major DNA test services recently modified their DNA reporting to re-name the haplogroup subgroup segments with their intent of further refining the reporting they provide. The haplogroup segments apparently aren’t sub-divided and named the same at each DNA testing company.

Most of your genetic relatives will actually fall outside of your haplogroup, because your haplogroup only tells you about direct paternal-line or maternal-line ancestors. Typically, the DNA mutations that define a haplogroup occurred thousands of years ago, so it’s possible that many pairs of people who share a haplogroup are not actually closely related.

DNA test reports can be confusing. To understand them means you need to spend a lot of time studying the explanation that the different services provide. Not all services use the same methods of reporting results. The software the DNA testing service uses may be specific to the particular DNA testing service and the results they report will be based on their particular software capability.

Percent DNA Shared by Relationship

To help in interpreting results, the following summarizes the average percent (%) DNA shared for different types of relationships. You may notice that several relationships share the same average percent (%) DNA.

The popularity of DNA testing has grown into an industry with many service providers. A search for the top DNA test providers will provide you with names and user satisfaction ratings for many of these service companies. MyHeritage DNA is rated high, LivingDNA is rated high, Ancestry DNA is rated high, 23&Me is rated high and FamilyTree DNA is rated high. There are many other testing services. Some offer more than just genealogical reports. Higher in cost, but valuable health reports are a service of several testing company’s. Health reports can reveal inherited risks passed from one generation to descendants.

One thing to note is that when these services give you the name of an individual from their database as a possible relative it is because that person has also submitted DNA samples to the DNA service that have similar markers. Further, if that person claims, (through the data they provided) a relationship to what appears to be an ancestor of yours the ‘educated’ assumption is that this is a valid confirmation of your relation to the other DNA submitter. It is not a guarantee of a relationship, but an ‘educated’ assumption.

As we said, we would like to hear from those who have had a DNA test. If you have a report that can be attached to an email we’d appreciate seeing a copy. If your report is not in a format that allows it to be attached right now you might scan the report, or use a digital camera (smartphone) to photograph it.

We have an offer by a descendant of Felix Powell (Feliciano DiPaolo) to pay for DNA tests for direct line male descendants of Joseph DePollo (Guiseppe DiPaolo). This offer is made with the hope of gaining another factor to confirm their relationship as siblings.

Send us a copy of your DNA report

Email the copy of your DNA report to us at; info@depollofamily.com   We will not publish the specifics related to any person’s individual report, but may in the future summarize all reports submitted.

If you (only male direct line descendants of Guiseppe DiPaolo) are interested in the offer to have a DNA test kit provided please send your request to the same email address noted here. We will pass your request along to the Felix Powell descendant who offered to pay for the DNA test.
