I thank you for all the effort trying to find Ann Mariah Nicols and husband John.I had another look at the info sent to me from Oz and it says.
Ann Maria burial Oct 1853 Grave site 242 St. Saviours Cem, Goulburn NSW
John Nichols Burial Oct 1869 Grave site 242 St. Saviours Cem, Goulburn NSW.
I don't know what else we can now do.
Appreciate all your help
