I guess we're cousins! My thread is through their son Willian Nelson Dickson. I believe I've seen the census showing your Mary and George. I have a bit of information on John (his parents and siblings) but not his birthplace though he was born in Ireland. Also have some info on Agnes. If you want to contact me off this forum let me know or if there's something specific I can help with. Do you have anything on John's birth or prior? This is exciting!
