Grace, I am so sorry but I never did hear that there was a message for me on the Seid site here and I haven't checked it for a couple of yrs. I recently got interested in the Seid name again since I just received a message from a lady, whose great grandparent is a brother to my husband's great grandparent.
I don't really know too much about the Seids. I do know that Wm. F. Seid was born in Maryland in 1850 and that his parents were born in Germany. Wm. F. Seid and his wife, Eliza A.(Stumbo) Seid had several children....Minnie, Della, Allen, Wilbur, Bessie, Nancy and Hattie. They were living in Washington County, Idaho in 1900, for certain, as they were found in the census there.
I hope that by now, you have found your husband's aunt. Good luck.
