I am very late to the conversation here but here is my two cents. The Robert Guy Colwell that you refer to here is the son of George Albert Colwell and Margaret Matilda Gibson and is my husbands great uncle. (he remembers him well). My husband's grandfather was James Earl Colwell, brother to Robert Guy. Robert (Bob) lived from 1896 – 1974. He never married and and lived his life on the land next to Earl in Woodstock NB. Robert was drafted to WW I but did not serve as he suffered from significant hearing loss. James was also conscripted late into the war and was training in England when the war ended. Hope this sheds some light . . .
