Your gr.grandfather John Anderson was the brother of my gr.gr. grandfather William Henry Anderson. John was a farmer born in Quebec, married Ellen Jane Draper May 10, 1881, in Aylwin twp, Ottawa Co., Quebec - it was an Anglican wedding. He and many of the other Anderson siblings can be found in the 1901 census in Aylwin twp, Wright Co. Quebec.
His parents were George Archibald Anderson (b.Que) and Martha Howard (b.Ire) (Martha's bro. Geo Howard lived next door in the 1881 cen and 1901 cen, and Martha named one of their sons Howard). They can also be found in the 1871 census of Fitzroy twp. George and a few of his sons were carpenters
Family history says the Anderson's were loyalists - haven't got that far yet. I've just started on this branch of my family but I've got more info if you like - email me
