Hi g,
Thanks for the extra info.
I have her Death Certificate and it states her father was John and mother is unknown. See attached.
Here
http://www.huntervalleygenealogy.com/forum/viewtopic.php?f=3...Nick stated there was a daughter called Annie.
As the Callaby name was so unique there could not have been too many of them in Jerry's Plains in the 1840s though maybe there was a John and also a Richard???
I will change Peter's birth to 1820 with the sources you have provided.
Do you know who the Miss Maria Callaby who died in Singleton in 1852 age 27 was related to?
