Hello Helen,
I see you posted almost a year ago - I have just seen it and hope you are still interested.
Eliza Jane Snoddy was my great grandmother, her son Frederick Joseph Tweed was my grandfather and my mother is Audrey (Tweed) Logan. My name is Jackie Logan and my mum Audrey is the family historian. She has a large archive of pnotographs and family history relating to the Snoddy and Tweed families. She would be delighted to talk to you and share her information. Please get in touch.
