Was Payant her married name? Do you know her husband's name? Do you know her maiden name? Does the death certificate list any other information? Do you know about when they moved from Canada to MN ?
I found these Payants in 1870:
Payants living in Faribault, Rice, MN in 1870 and listed as born in Canada:
Albeno Payant b c1866 White Male
Angeline Payant b c1812 White Female
Clement Payant b c1830 White Male
Georgiana Payant b c1850 White Female
Joseph Payant b c1844 White Male
Leroy Payant b c1865 White Male

Mary Payant b c1842 White Female
Mary Payant b c1863 White Female
Odilli Payant b c1831 White Female

Also, there seems to be only a few Payants in Ontario, but there is a crap load of them in Quebec. I didn't find an Albina, though.
