1- Sophie Rocque get married with Joseph Bousquet february 23, 1852 in St-Hyacinthe.
2- Israël get married with Rosalie Brunelle january 22, 1877 in St-Hyacinthe. They had a son Israël Henry born july 9, 1879 in St-Hyacinthe.
3- For Louis Bascom born march 8, 1841 according to your E-mail may be well Louis Bousquet born march 7, 1845 in Shefford. I think about this possibility because Louis was the brother of Israël and I have good reasons to believe that he emigrated in USA. I don't know where he get married and with who.
4- For Louis + Mary Philemon Lattabush and Pierre + Melina Meron, I can't find anything without more clues.
Please, send me, if possible, all the informations you had about the Bascom. If they were born or get married in Québec, I will be able to identify them.
