Thanks, Nancy. I'll take a look at the 1930 census my next time in the library. The ages at which they married must refer to their first spouses, if this is the correct couple. Both of Bettie's parents were also born in Alabama, not Arkansas, but of course census answers depend on who's giving them.
Do you happen to have the url of the online database for the Cooke Co TX probate index? I looked in Cooke Co on the USGenweb but I didn't see one, but then again, I may simply may have missed it.
