Hello Pamela, I have done some research on this family with another cousin and we never figured out WHOSE child Louisa was. I also think that is the only record I have on her but of course she could have married before the next census. Her uncle Edward was my great grandmother's (Marie Wilhemine Bridget Gagne Robinson) brother and one of ten children, one of whom must be her parent. The family spelled the name Gagne and hailed from Montmagny, Quebec, Canada and came to the USA in the 1870's. Her grandparents were Jean Baptiste Gagne (1820 -1898) and Marie Louise Fournier Gagne (1826 -1890) and there are many postings on them on the genealogy.com websites. I have not been actively researching my family for a while and came by your posting by chance. I have a lot of info on themand if you would like to see it I can get it to you. How are you related?
