I would like to know what happened to Theresa, too. Have you found her? I've done many different and loose searches for her, and still come up empty. I see her two sons with Elon are also buried in Maple Grove Cemetery in Ellsworth. I can't find a marriage to indicate she remarried, I can't find any death information to indicate she died, and I can't find her daughter, Susannah Stuck Cummins to see if she's there.
