My family tree stops dead with my grandfather, James Irving Seward. He was supposedly born in Arkansas in 1900, the youngest of several (perhaps nine) children, joined the Navy, got married and moved to Wyoming, etc. My grandmother said that he had sisters who had married and moved to Denver. I have his social security number and death certificate (which gives his parents' names as "unknown") but just can't turn up any connections for him. Would anyone out there have a lead or an idea about what to try next?
