Yes,most of them changed the name.My g-grandfather was born Remi Zenophile Roussard dit Lefebvre in 1843 in Laprairie, Qc. On marriage in St Clair MI in 1865, he was Syrophile Lefevre, by the 1870 census he was Nelson Bean. All his descendents carried the Bean name. I do know that members of that family immigrated all over the midwest, and New England too. Let me know any names and dates, I am actively researching right now, and have found family members widely scattered.
