I have found where I got John Walters & Catherine marrying - a researcher had posted this info asking for anyone who knew anything on them:
WALTERS, JOHN. Lampton Park, Lachlan River married and CATHARINE
MURPHY of Lachlan River 5 Oct 1853 at Cowra, N.S.W
Children:
Elizabeth b. 12 January 1855, baptised 17 May 1855 by B. Murphy
(Father's name: John WALTERS, mother's name Catherine KELAHER )
Joseph b. 16 Apr 1858, Currawang Creek, father John WATER, age 42,
mother CATHERINE, age 42, formerly SHEAHAN (married 1853 Cowra).
Previous Issue Elizabeth 4.
Death of Joseph 15 July 1859, Moppity Station near Binalong, age 16
months. Father John WALTERS, mother Catherine, formerly KENEHAN late
MURPHY.
The "late" Murphy would confirm they think James is dead.
I haven't got the funds to confirm all of these certificates so have had to trust what I find, if I think it trustworthy. (

) Some info I have found I have disregarded as it has not gelled with what else I have.
More coming...
