My families last name was Mantha Di Guilbeaut or Imbeault. My great grandfather George shorten the family name to Mantha. They all come from Canada. My grandmother was a Therrian (Anita Louise) and she married George. I am having trouble finding more about the Mantha's and DiGuilbeaut families and also my great great grandmother, Margaret Frank who came from Bohemia with Francis Meindel or Meindle. Any help would be awesome.
