I think we maybe researching the same line. I can't get beyond my gg-grandfather. Jean-Baptiste (m. Olivine Baillargeon). I may have made some progress through MA census. Jean-Baptiste's father and your Jules may have been brothers. I found a Jule Gomeau (phonetic spelling I'm assuming) age 55, Betsey 49, Lewis 18, Victor 16, Felix 14 in Southbridge MA in 1880.
