1901 Census shows DOB as 10/18/1839, however, birth records for sibling Edouard in Aug/Sep 1839 would not allow for his birth being in 1839. St. Hyacinth birth record for "Damien" Kavanagh shows the following, although it may not be him:

KAVANAGH, DAMIEN Bapt Oct 17, 1841 Born Sept 7, 1841
Parents Edward Kavanagh and Helene Bonin
Godparents Desire Josse and Anne Foret
B 29

This is probably Daniel in spite of census and tombstone both showing 1839.
