Hello,
I am not a Sykes - but saw a name I have information about...There is a Minnie Sykes, born in Monticello, MN in 1897 (where, ironically, I actually live) who married my great uncle, Orrin Smith. They relocated to Coeur D Alene,Idaho where she died in 1981. I wonder if this is a missing twin?
Good luck!
Patricia
