I can't seem to find this guy anywhere before 1900!! Would it help to have the names of all his daughters spouces? Maybe you can find someone else researching this family.
I found on the CA Death index a Wlm. Henry Gade b. 1876 WI. Do you think it's possible that he was married before moving to CA?
Do you have a copy of his death record? 14 Jan 1926??
