Well, I just hit a new, temporary brick wall in my family tree. I just noticed a new DNA match in the 2nd to 3rd cousin category in Ancestry last night. This person is matched to my father’s line, and has to be matched through my paternal grandfather or one of his siblings; his shared matches were the first clue. Since he is matched to ALL the lines of my paternal grandfather, he has to be descended from that generation. This is not the first unknown of descendant/DNA mystery/family secret match from ANY my lines. I have found and solved many unknown of children/descendants/family secrets that no one knew about; I will try to blog about those stories when I have time. This one just happened, so it is still fresh in my mind. I know ALL of the descendants of those lines, and had published my descendant books on those lines about 6 years ago, and he was not one of them. Hmmmmmm, a new DNA mystery to solve! Challenge accepted! 😉 So, time to get an early start and wake up with my morning tea; I’ve got a new DNA mystery to solve, and my challenge awaits! 😉 His centimorgans shared with me are 201. This leaves him (only according to his centimorgans) most likely matched as a 1/2 gg-aunt / uncle; a 2c; a 1/2 1c1r; a 1c2r; a 1/2 gg-niece / nephew; a 1/2 2c; a 2c1r; a 1/2 1c2r; or a 1c3r, and a less probability (but still possible) as a 1/2 c3r †; a 1/2 2c1r †; a 3c; a 2c2r; a great-great-aunt / uncle; a 1/2 great-aunt / uncle; a 1/2 1c; a 1c1r; a 1/2 great-niece / nephew; or a great-great-niece / nephew (according to the DNA Painter Shared cM Project tool). Okay, time to get going on this! He had an unlinked tree with only 3 people in it: him as private, his father’s name and date and place of death, and his mother as private. The first thing I did was quickly build my own tree for them in Ancestry, as always. I found his father’s information right away. I found a marriage for his father, and added that spouse as a possible (who I thought at first) mother. I then added a few male and female children born to them with no first names or any other info, as I usually do, and searched for them. I found 2 children born to them, but neither had the name of my match. This was all in the first 10 minutes. Stay tuned for more in Part 2!

Have you and a sibling taken a DNA test and were either shocked or confused about why you didn't have the same ancestral DNA results or ethnicity percentages, when you have the same parents? Did you think that you and your sibling should have the same exact ethnicity and percentages, well, because, you're siblings? Not exactly. Let's take a look at why this could happen in genetic genelogy! DNA Ancestry vs Cultural Ancestry: Don't siblings Have to Have the Same Ancestral DNA? No, you and your siblings do not necessarily have the same ancestry results in your DNA. DNA ancestry can be quite different than cultural ancestry. Think of it like a bunch of colored marbles in a jar, and that each color represents a particular ancestry. Ancestral DNA Mini Experiment: Pretend that you have a jar of colored marbles, and that you cover your eyes, reach in, and pull out a handful; then your sibling does the same. Do you think that you and your sibling will pull out the same combinations? The answer is most probably not. It is the same thing with your ancestral DNA. Random Mixture of DNA: Yes, you will each get 50% of your DNA from your mother, and 50% of your DNA from your father, but that DNA isn’t passed down in a single block; not every child gets the same 50% from their mother or the same 50% from their father, just like in the little jar of marbles experiment above. Each child will get a random mixture of that 50% DNA (a particular colored marble) from each parent. Full Ancestry vs Mixture of Ancestry: If your parents each have 100% of a particular ancestry (this is not the usual case nowadays), but each has a different ancestry than the other, you and your sibling should each get 50% of each. It’s when your parents have a mixture of ancestry (usually the case) that you and your siblings will have different ancestral DNA results from one another. Since most people are made up of many ethnicities, the mixture in the marble jar will be more varied, thus each handful pulled out has a higher chance of being different from the previous handful. Interactive Questions: Have you taken a DNA test and were either shocked or confused about why you and a sibling didn't have the same ethnicity results? How different is your ancestral DNA with your sibling? Do one of you have more of a particular ethnicity than an other? I'd love to find out how different you and your siblings' DNA ethnicity is!
