Hi Robert.I found some census information for you:

I think I found Clovis in the 1880 Census, living in Allenstown, Merrimack, NH:
Morrow, Clovis, age 56, b. 1824 Canada
Morrow, Dileanor, age 48, b. 1832 Canada
Morrow, Eleanore, age 26, b. 1854 Canada, occ- Cotton Mill

Morrow, Noe, age 17, b. 1863 Canada, occ- Cotton Mill
Morrow, Annie, age 16, b. 1864 Canada, occ- Cotton Mill
Morrow, Philip, age 14, b. 1866 Canada, occ- Cotton Mill
Morrow, Selina, age 12, b. 1868 Canada, occ- Cotton Mill
Morrow, Clovis, age 8, b. 1872, At School
Here they are in the 1871 Canadian Census, living in St-Christophe, Arthabaska, Que:
Moreau, Clovis, age 48, b. 1823 Que, Farmer
Moreau, Delima, age 37, b. 1834 Que
Moreau, Delima, age 18, b. 1853 Que
Moreau, Napoleon, age 17, b. 1854 Que
Moreau, Noe, age 8, b. 1863 Que
Moreau, Annie, age 6, b. 1865 Que
Moreau, Philippe, age 5, b. 1866 Que
Moreau, Salomee, age 4, b. 1867 Que
Moreau, Zoe, age 1, b. 1870 Que
I found a marriage for Clovis & Delima:
Clovis Moreau, son of Prudent & Marie Marthe Couillard
m. 9 Aug 1852 St-Eusebe, Princeville, Arthabaska
Delima Lalier, daughter of Francois & Suzanne Paris
It looks like some of the children were born in St-Christophe, Arthabaska, and some in St-Paul-de-Chester, Arthabaska, but I could not find a Clovis Moreau, born around Feb 1872.They did have an Alphonse, b. 18 Nov 1873 St-Christophe.So, that is frustrating to me.
Hope some of this helps.Annie
