Even though I don't have a copy of Denis Savard's Arsenault Dictionary, 30+ years of experience comes in handy.
Found the following in Gabriel Sarrasin's Dictionnaire des Familles de St-Didace (p 23).
Alfred Arsenault, died in Providence in 1913 (37y.); his body was brought by train to St-Didace, where he was buried on 5 May 1913.
His parents' marriage:

Leandre was baptized at St-Didace on 13 Mar 1853; he was elected a trustee of St-Didace parish on 4 Dec 1912.He was buried in the neighboring parish of St-Edouard, QC, on 30 Nov 1916 (65y).His widow, Oliva (or Eva) died at St-Edouard, but was buried at St-Didace on 20 Mar 1926 (72y).
They had the following children:

Antoine & Eloise (or Louise) are both buried at St-Didace, him on 5 Dec 1878 (71y) and her on 18 Jul 1881 (70y).
Am sure with this springboard of info, Richard Saunders can fill in the rest of the missing details for you back to your Arsenault ancestor, Pierre.
