My name is Lynette O'Brien and the Seufert family was a prominent family in The Dalles, Oregon for many years. Francis Anthony Seufert started a fish cannery business here with a brother, unsure of his name. He had 3 sons and a daughter; Arthur, Theodore, Edward, and Lillian. Edward had two sons named Richard and Edward Junior. I know Richard was married at least 2 or 3 times, but I am unsure if he is the same Richard you speak of. I don't remember any of his marriages producing any children. If I can be of more assistance, I hope I can be of help.
