Hi Chloe: You're right. I did find more information with regard to my initial query, though not on who Moses Bacon or Catsey Thomas' parents were.
I did find Bettie (Mathews)Bacon married to William Finch in 1920 (though not yet a marriage record) and she is not there in 1930. I believe they divorced.
Found lots on Samuel Bones and his birth family through both census records, books (both hard copy and through Googlebooks), newspaper stories (via the Godfrey Library's newspaper portals) and city directories on microfilm.
But you have prompted me to go back to WWI and WWII draft registrations to look at Bettie and Abijah's sons, as they were not fully available when I posted my query.
Abijah probably died in Cooke Co. TX but I need to check cemetery and probate records. If not there, then I would next check Fisher Co. TX.
I will keep you in mind when I look again for Moses Bacon and Catsey Thomas' parents.
