Doing some long overdue cleanups and found a letter from a lady here in Australia who contacted me re the above names. She is a descendent of James BIRRELL and Helen PETRIE, their son Thomas BIRRELL was born 17 Feb 1844 at Plattsburg and was her great grandfather. As the letter is a few years old, I have looked up the name and address on our White Pages online and she is still at the same address. If she is online with us, she may speak up if not anyone wanting to contact her can email me for the address. Annette in Cowra NSW
