Found - Ances of Robicheau ,Digby Neck
Thanx to Fred @ Union7, it appears that the father of "Jarvis" Robicheau (real name Gervais Robichau) was Bernardin Robicheau, spouse, Isabelle Trahan. Gervais Robicheau was married to Helene (and not Helen) Theriault in 1840 at Ste Marie Baie (read, St Mary's Bay). Given this information I was able to traceances at Ivan Robichaud web site (robicho2nbnet.nb.ca) to one Etienne Robichaux/Robicheau/Robichaud, born 1638 and died 1686 at Port Royal N.S. Etienne had a son , one Charles Robichaux (born 1667 Port Royal, died ca 1737 Port Royal) married twice, second wife was Marie Thibodeau, his 3rd child (by wife #2) was named, Pierre I "Cadet" Robichaux (born 4-26-1707 and marr to Suzanne Brosseau about 1734). The son of Pierre Robicheau/Robichaud/Robichaux was named Olivier Robicheau/Robichaud born ca 1742, @ Cobeguit, Acadie; and marr 1769, at Pte. du Diable, Halifax, to Madeline Hebert. The son of Olivier Robicheau/Robichaud was Bernardin Robichaud/Robicheau born 1768, wife Isabelle Trahan. E C MacFarland, 2 Pine Lane, King William, VA 23086.
