After working on it (slowly) for some time, I've finished transcribing all of the individuals identified in the Tombaugh History into a family tree (GEDCOM file). I've hosted the GEDCOM in an online website software package that is searchable on my website at http://www.Tombaugh.org/genealogyhttp://www.Tombaugh.org/genealogy.
I've found a few descrepancies which I'll post separately in individual posts to see if anyone can offer any additional information.
I would love to update this material, perhaps as a "community effort," to include corrections, updated information, additional sources, etc. I do have some additional information that others have already sent to me, or that I've collected, that I'm going to begin incorporating next...
I have not had the opportunity to complete much additional research at this point, as I thought that having this effort as a "base" to start from was the best way to begin.
