I have been looking for some (Dessein) St Pierre family members to complete my Family Tree for years. I'm wondering if anyone out there could help me, so by placing this info on our web site may help.

I have found Xavier or Olivier Dessein St Pierre who was married to Angelique Lagace in the Diocese of Rimouski registers. He is listed as having four daughters and no sons listed although one of his sons was my ancestor. His four daughters were:
Cleophee who married 1) Nov. 12/1850 at L'Isle Verte, Joseph Paradis
2) Sept. 30/1886 she married in Trois Pistoles, Francois Dancause
Olivier's daughter Angele married at L'Isle Verte, Jan. 13/1863, Antoine Bastille
Henriette married at L'Isle Verte also, on Oct. 18/1869, Paul Richard
Virginie marrried at L'Isle Verte on Aug. 14/1871 to Pierre Pelletier

Some additional info I have on the family:
Francois St Pierre s/o Olivier and Angelique Lagace who passed away at l'Isle Verte at age 34 on Oct. 8/1868...

Joseph St. Pierre age 26 bachelor/farmer born Isle Verk (L'Isle Verte) residing Pembroke son of Oliver St. Pierre and Angelic Legace to Mary Brozain (Brazeau) age 22 spinster born Vaudreuil residing Pembroke dau of Antoine Brozain and Emily Belare. Witnessed by Alfred Willett and Hiacinthe Bertrand of Pembroke. Both Roman Catholic married at Pembroke Sep 28 1869 by Rev. Boucher by licence. Reg No. 2096. Taken from as above, Vol 1

Joseph (AKA Georges) St. Pierre was supposedly born in L'Isle Verte, QC in 1843.
Census in Kamouraska 1851 has Oliver (Xavier) St. Pierre and wife Angelique Mignier dit Lagace and son Francois. No Joseph.

Joseph can't be found on either 1851 or 1861 census at L'Isle Verte. There is no birth or baptism for him , a record before his marriage in 1869 at Pembroke, Ont. can't be found so far.

He is from outer space or under the witness protection plan. (I stole that from somewhere)
