Hi, I found a few clues here in Illinois. Since your grandfather was born in 1855 and lived in CT all his life, it doesn't seem likely his family came to Illinois in 1860. The first I can find of them is 1910 on Heritage Quest. I assume these are relatives. 1910 Kankakee County, Kankakee Township, 5-WD Joseph Pelletier, 48, Married 1, 28 years, 9 children, 6 living, born IL, father Canada/French, mother Canada/French, Laborer, Odd Jobs Wife (name illegible) 42, housewife, born Iowa, father Germany, mother France Mary, daughter 23, single, born Illinois, etc., housework, private family Frederick son 18, single, born Illinois, etc., factory worker Walter, son 17, single, born Illinois, etc., helper in Machine Shop George, son 14, single, born Illinois, etc., factory worker Monee, son 6, single, born Illinois, etc. 1910 (same location) Joseph P.
