Does anyone have knowledge of the Ouellette/Willett family that lived in Killingly, CT recorded on the 1880 census? Information as it appears on the census:

Jerome, age 38 & Sophia, age 37,
Children: Jerome, 15; William, 13; Romah, 7; and Rosa, 2.

There are other children, not listed with the family on the census: Harmides b. 1880; Joseph b. 1866; Rosalie d.1878 CT; and a Sophie b. 1871?

Thanks for your help.
