Dear Edwina, Wow what a wonderful surprise to hear from you especially considering it is 7 years since I posted that message.
I did often wonder if Ralph may have been a cousin of my James who married Ann Fergus/son in 1833.Their marriage is listed on family search.org as is the birth of their 4 daughters.It appears though that only 3 came with them.Not sure who Agnes is either, perhaps James sister?
Great to hear from you.I am in Sydney suburbs - where are you please?
Kind regards, Julie. (julieperrim at yahoo dot com dot au)
