Hi William.It's been a while.What we know:Folkert Dow b. 1808 Bedminster, NJ is related to Abe Lincoln's wife.Jane Dow b. 1806 Bedminster, NJ.Are Folkert and Jane siblings or cousins?As far as I know, I am not a blood relative of Folkert.His descendant, John Danbury Dow, married my great aunt Lydia Smith.However, I have a cousin descended from their son, Charles Dow and Maude Mackey. Also, I am a direct descendant of Jane Dow and Martin Ruckman. Have you discovered more info on Dow/Todd in Bedminster area?
