Robert, just to clarify.
My line is ME > Maynard Stills > Melvin Virgil Stills > Smith Alexander Stills > Uriah Ricker > Elijah Ricker > John K Ricker > Peter Ricker (German Immigrant).
Betha McCoy (Wife of Melvin Virgil Stills) > Julia B Davis > Mary Emma Cutshall > Nancy Ann Ricker (Sister of John K Ricker) > Peter Ricker.
Smith is "adopted" and raised by the Stills, his father Uriah only had one child, Smith. So I would need to find a Male Ricker descendant of Elijah Ricker for the Y-DNA37 test.
I do not have to worry about Bertha's Ricker mix as that would not show up in the Y-DNA37test. And I should have my Father Maynard tested. I will study the Confirmation Aid futher. It looks intersting and helpful Thank you.
