William had a daughter by another Darug woman before he married Sarah, the daughter is Jenny Swift.
I will add her info on another page, I am in contact with a few of Jennys family.
These are a few of the children of William and Sarah:-
William N.T b. 1862 (Castles)
Maria Catherine b. 1864
m. William George Smith.
I will add more as I get the names, or if family can add the names would be wonderful
