My 2nd great-grandfather was William Arthur Dupont (1874-1957) he married my 2nd great-grandmother Rosabla (full name: Marie Eugenie Rosabla) Juneau (1877-1902).
William's parents were Joseph Andre Nazaire Dupont (1843-1933) and Marie Hermenie Leonide Deguire (1846-1899).
Rosabla's paretns were Edouard H. Juneau (1851-1902) and Marcelline Sauve (1850-1901).
I have a very large personal tree on ancestry.com. Though, I know I have some errors for my Juneau side.
