William is Esther (Van Slyke) and Lyman Stow's son.On your listing where it says that William was born in Canada, that is wrong, it must have been a copy error.You can see on their marriage info that it says he was born in Flint, MI.It is also wierd that they list him as a policeman.With their marriage info he is listed as a carpenter.He is listed as a carpenter in the 1870 census where he is listed with his mother.And then again in 1880 you find the family in Colorado and he is listed as a carpenter.I wonder how the family ended up in Chicago?William's older sister, Hannah lived in Oakland Co., Mi married to someone by the name of Buzzel or something like that.His older brother, Lyman Jr., lived in Detroit.Three of his step brothers/sister moved to California. In the Probate records of Lyman's estate they write back to Michigan and the letter is included.I don't know what ever happened to William's younger sister.
I have a copy of William's marriage and the birth of Henrietta.They are the actual entries into the ledgers. I can not attached them to this message, I would have to email you directly.
Lyman Stow Jr. wrote a book that mentions a bit about his growing up in Michigan.The book is called "Karmenia, or What the spirit told me".He was new age or occult in the 1880.The book is a little different but it does talk about the death of his father and mother.You can read it on line at Google books I believe.
Do you have a picture of William Stow? Or don't your pictures go back that far?
PS - I have information about the Van Slykes if you need anything.
