When my great-great-great grandparents James Dunham (1788-?) and Betsy Gilpatrick (1795-1860) were married in 1814 in Orland, Hancock County, Maine, they created a link between my Dunham ancestors and the ancestors of John Hancock, signer of the Declaration of Independence. Governor Hancock is actually my second cousin. He is seven times removed because he and I are separated by seven generations. This chart lays it all out.
Happy Independence Day!
