The correct word should have been geneticist. Also, I believe I should have posted to the Autosomal board. I am not familiar with the other DNA test. I apologize.
I took the test to help with three family lines that have been dead ends for years. Initially, I believe my sister took the test because she was curious. Comparison of our results indicated differences; so, we are waiting on our parent’s results. The hope is that our parent’s results will help resolve some of the ambiguities encountered while applying the results to our tree. The point I attempted to emphasize in the initial post is that testing multiple immediate family members has distinct advantages.
In my opinion, given the current format for the Autosomal test, collaboration between members is beneficial and in some cases may be critical to resolve issues. For example, one member and I shared a proven match. I matched another member with the same surname but not to a specific individual or locale. I contacted the individual with the proven match and ask if the other member was on their list of matches. Maybe this was simply a case of coincidence but in the end three members gained new information for their respective tree.
In my post, I stated that in some cases excluding a possibility [through DNA] may be better than a match. I have three possibilities that could be my great-great grandfather. There are no records (only the 1870 Census). If I could identify family members from these three possibilities that have taken the test and search my father’s, my sister’s, and my results for these members, no match would be a starting point. Granted, no match or even a match is not absolute proof, but in this case I have nothing and this information gives me something to work with.
Unfortunately, these forms of collaboration require each member involved to manually search their results. As you know, this takes a little time. I do not understand why Ancestry.com will not add a search function to the DNA results.
