I am researching the same person. I have Marie and Zacharie having children until at least 1782, 6 in all. She was described as Sauteuse , which may have placed her birthplace in the Drummond Island area. do you have marriage or death records? I would like any information that you can provide. I also have her last name as Omagash.

Children of the union of Zacharie CLOUTIER (no parents given on marriage record) and Marie Josephe MANITOUKOUE (also shown as OMASKAS; "Sauteuse"; no parents given), married 1780-11-21 at Oka, are:

Charles, baptised 1780-11-20 at Oka (ne "il y a quelques annees" [several years old]) who married Madeleine CHABOT on 1797-02-13 at Laprairie (stated age as 21)

Genevieve, born 1779-11-14, baptised 1780-11-20 at Oka, who married Jean Baptiste MESSIER dit ST. FRANCOIS dit ST. MICHEL on 1797-10-26 at L'Assomption de la Pointe de Montreal de Detroit.

Joseph Benjamin, baptised 1781-10-10 at Oka

Marie Madeleine, baptised 1782-06-29 at Oka

Marie Josephe, baptised 1785-04-11 at Oka

Francois (no baptism record; "sauvage") who married Elisabeth (no last name) a "sauvagesse", widow of HANANT CHIOUAPAIS ("sauvage") on 1799-07-11 at Maskinonge.
