Can anyone tell me where there is a link/proof that Bettie and Josie (Josephine) were sisters?
I agree that William and Benjamin were brothers, just not sure about that pair of wives as sisters.

There was a pair of Hall sisters who married Gragg cousins, William and Benjamin's sons.

Birtha E Hall - m: Ed (Edward) Gragg
(William's only child with Bettie)
Pearl E Hall - m: James Olin Gragg
(Benjamin's son Olin)

Also - Can anyone tell me when Bettie (Atkins) Gragg re-married to a William Henry Jones? (had to have been 1900 or later)
