P1B: BACKGROUND MATERIALS:
If you’re not familiar
with DNA testing, here are some topics you might explore. (You can view them on
line, or print them. Personally
I prefer “print”!)
Parts 3 and 4 are not
directly related to this y-DNA project. However our
members often order additional tests to cover these.
Mitochondrial DNA follows
your female line, but it is difficult to use for genealogy.
Autosomal DNA looks at
your total DNA picture, looking for all your family lines. It might pick up a
Coffey ancestor, but it has a limited range. It probably will only work if
there is a tested person out there who is your third cousin or closer.
In 2017 I did an update
review for the Coffey Cousins Clearinghouse convention. It covers some of the
material in the “Basics”, but goes more into the
geographical relationships between various Coffey groups.
