I found this in the 1871 Canadian census:
Liversant Jacques Male 63 abt 1808
Liversant Phebée Female 48 abt 1823
Liversant Angele Female 24 abt 1847
Liversant Joseph Male 22 abt 1849
I would guess that Phebee is a second marriage, but so far I haven't located any marriage for Jacques.
still poking around :)
