Re: John Dura/Duryea m Permellia Davis Central NY

John A. Duryea m Permelia Emaline Davis. John is my wifes g-g-grandfather. All of the information that we have is from family records and known information. My main interest is to find out how this family is a relative of the Duryea Automobile family, which is a known family fact, but is not proven by sources. Please help.
