Hello again Steve,
Sorry if I have misled you with the Canadian connection. Just that we have always heard and spoken about an Annie O'Dwyer somewhere in the family and it was always assumed to be Alexis Snr's wife but we now know that he did marry Margaret Duggan. I have found info about Titus since his father Robert and brother George witnessed his second marriage to Agnes Lalonde in Cornwall, Ontario. However please stay with your own evidence. As I said, I wouldn't give anything different without solid proof and I have not found this with regards to Alexis and Margaret Duggan in Canada.
Going back to the Susan and George you mentioned previously, George is my mother's youngest brother. The actual copy of my Grandpa Alexis' census form does show that he has left some of his children off. I'll forgive him - perhaps he was tired or imbibed a little too much beer that day. My sister has my mother's birth certificate and she was definitely born in October, 1906 so Louisa's date of birth is still a year out. I had no idea that my Grandmother Charlotte's sister Susan married Alexis' brother ?Charles which does create confusion but gives us a challenge - enjoy!
Best wishes, Brenda
