Lois,
I'm going in circles about this. Another scenario could be that this granddaughter Catherine Kaighin was adopted by another of gradmother Eleanor Cannon's children and kept her last name (although unlikely). I think the answer may be found after discovering who Joseph Woods was. Anyway, I've ordered several films from LDS in an effort to track this down. I'll let you know in a couple weeks after the films come in if I find anything.
