In the 1905 Census, Peter is listed as living with Raphael [Ralph] and Julia. Relationships are not given in this census but he was probably a son.
Raphael was married to Julia Michaud. That info is from records of some of their children. On Raphael's death record, his Father is given as Raymond but his Mother is not listed. By birth year and location, he was probably the son of Raymond Daigle and Eleonore Martin married 11 Nov 1845 St Luce, Frenchville, Maine.
