[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Whoa!! I’m on ancestry and this is NOT enough info to say that is not your biological grandfather. [/quote]

What do you mean? The centimorgans are in the low 400s between all my cousins and me. Thier's, however, are in the 800/900s. Nearly every website we have researched says the relatedness is either they are my half-first cousins or like great aunts or some other impossible scenario. Plus, it has connected me to relatives on "the other side" (mom's side) that don't show up in the cousins' list of relatives. [/quote]

I have oddly varying percentages with different cousins. For some reason ten to 12 percent of a match with his three cousins on his moms dads side but only five percent with my dads first cousin on my dads moms side. I don’t think it means anything. [/quote]

Your dad’s first cousin is your first cousin 1x removed. The percentage should be low.

The relatives I'm referring to are first cousins.[/quote]

You’re not getting my point. I’m comparing the percentage of DNA I share with cousins with whom I have the same relationship. First cousin once removed on one side of the family versus first cousin once removed on the other side of the family. I have a 7% difference in DNA sharing amount with cousins whom I have the same relationship. Just because you share a different percentage of DNA doesn’t necessarily mean anything even if it’s the same relation[/quote]

DP - there’s also evidence that shows the percentages are more accurate when it’s a woman being tested versus a man, so if some of these cousins are male versus female  it may account for some differences in percentages. [/quote]
