19Sallie Williams' death certificate states that her father was named 38George Williams.1 He seems to have had a relationship of some kind with 39Elizabeth Norris.2 Based on when his children were born,1,2 one can guess that 38George may have been born roughly circa 1855.

See 19Sallie's profile for more information on the (unfortunately inconclusive) research I've done to identify 38George.
