My grandmother Lily Seymour was a sister of Inez. I remember Inez and Hilda McGuire.
Lily and my father lived with the Daniel and Inez family for several years after Lily was divorced. My dad and Bill Bacot were life long friends (and cousins).
We have a summer home in Charlevoix and have done extensive research on the Supernaw and Seymour lines.
I would love to talk to you if you are interested.
