Re: how to interpret results #dna
To begin with, why do you think that you are related to these
Kochs? What do your Y-DNA tests indicate?
>from the little that you write, it looks like all three of you are
We Ashkenazim are endogamous and we share much of the same genetic
cocktail. Therefore, total centimorgans are not so useful for
us. Largest segment are more helpful.
To get an idea of how meaningful these totals are, I analyzed the FF
data fo a cousin on which results I am now working. She had about
1980 matches with total strangers which I divided into ten
deciles. Below are the deciles and the total centimorgan ranges in
each of them.
107 - 157 ( 50 )
97 - 107 ( 10 )
90 - 97 ( 7 )
84 - 90 ( 6 )
78 - 84 ( 6 )
73 - 78 ( 5 )
66 - 73 ( 7 )
56 - 66 ( 10 )
43 - 56 ( 13 )
20 - 43 ( 23 )
As for a town in common, think regionally. Our ancestors often moved
within regions and some locations indicate the likelihood of
migration (think Odessa). When you identify a likely relative,
identify the regions and ask about migrations.
