My grandmother was our family researcher along with my 2nd cousin in the 80's.
I've found myself unknowngly following in her research footsteps a couple of times which is kind of cool.
Names: Gibbens, McCormack, Womack (CA, MO, TN, VA) and White & Hirn in (Iowa & Wyoming.) Warner, Jeffries, Stott and Dowden (Iowa, Indiana, Maryland.) Marnin, Muthler and Mooney (New Jersey and New York.)
In particular, I would be very interested in talking to any Marnin, Muthler and Mooney descendants as we lost contact with that side of the family beyond two generations. Please message me here.
