Genealogy Brick Wall: Another New DNA Mystery Match-Part 5
Continued from Part 4
Continue with me on my genetic genealogy journey of a temporary brick wall for yet another new DNA mystery match that had just showed up when I already know all the descendants in that line, from Genealogy Brick Wall: Another New DNA Mystery Match-Part 4!
I left off last by working a bit on his parents’ lines just to gather the info I needed to see which of the lines was the connection, while waiting on working numbers, then comparing yearbook photos of his parents and their siblings to my grandfather and his siblings, to no avail. I had worked a total of two hours on my case already and decided to stop and continue the next day.
Good morning! Okay, time to get going on this and try to finish up. I’m going to need a pumpkin chai latte for this! Regular tea just won’t cut it this morning; I need something special to help me focus better and get this figured out! 😉
More Centimorgan Relationship Elimination:
Back to the Centimorgan relationships: I’ve got to make sure I take out every possible matched centimorgan relationship in DNA Painter that is not directly descended from my grandfather or one of his siblings because my match has matches to my grandfather’s paternal and maternal lines; therefore, he has to be descended from my grandfather or one of his siblings. Anything above my grandfather’s generation is now out, otherwise my DNA match would only be matched with my grandfather’s paternal line matches, or my grandfather’s maternal line matches, not both. All the possible match relationships of my match being descended from a possible half sibling to my grandfather are also out, for same reason as above.
After discovering my match’s and parents’ ages, anything above my generation is also out. I now just need to focus on my match being in my generation and one generation below, with a smaller possibility of being 2 generations below.
I am now left with: ½ 1c, ½ 1c1r, ½ 1 c2r, 1c1r, 1c2r, 2c, 2c1r, and 2c2r (½ g niece/nephew not possible).
If I also go with the higher probable percentages, then I only have 2c, ½ 1c1r, 1c2r, 2c1r, ½ 1c2r left to work with.
If I focus on my generation and the generation below only (going off my match’s and his parents' ages), then I’m left only with 2c, ½ 1c1r, 2c1r. This narrows it down significantly.
If I check those relationships with the histograms in the DNA Painter Shared cM Tool, there is more of a chance of my match being my 2c, ½ 1c1r (and 1c2r if I go as far as another generation below), but this is just a guide only.
Now I need to work with these findings, along with dates and places of my grandfather and his siblings, compared against the same information needed from my match’s lines.
Wow, who knew what a special pumpkin chai latte could accomplish! 😉
Stay tuned for more in Part 6 where I get down to the nitty gritty, and see what I deduce by these comparisons! 😊
