Thank you for the lead. The Edwards step-siblings are why I'm interested in this line. Their parents, Harvey Edwards and Callie Evans, are something of a family mystery. They moved out to Texas sometime after their daughter Eygine (?) was born and do not appear in the 1900 census (that I have found). Harvey must have died between 1900-1908, because on the 1910 census Callie has been married to Tom Green for two years. I have tracked down a few of their children hoping I could get some information that way, but no such luck. Now I've come back to trying to track down Callie herself. I know she's somewhere!
