Hi Roger,
Sorry I haven't answered your e-mail. Still trying to find my way around web sites.
Your branch of the family tree is the same as mine. I am descended through William who was born in 1833. From what I can gather he went to Scotland where he had a son, named William Crellin.
William Crellin came to Australia and married in 1900. He lived in the Singleton area, and most of his descendants lived and worked in the Newcastle area.
I can give you more information if you want it. Can you help me with any other descendants of William and Amelia.
Regards
Dawn
