I did find something that might lead to something for this census.
In the Drouin there is an Hermine married to Joseph Lahaise(one of the 17 variations/dit of Lahaye) on 6 jul 1880(10 year after the census?) in St-Ours. Daughter of Félix and Sophie(Sophia?) Bousquet(there is a "dit Larose" for Bousquet)
