“La Revue du Barreau de la province de Québec, Volume 13" By Bar of the Province of Québec. page 29:

'There was another case in 1932, Ex parte Edward Francis Trainor (14), which was decided by Judge Albert de Lorimier. It does not appear, however, from the record that this was actually a change of name as it was made to appear as the correction of an error. No jurisprudence was cited. In the birth certificate issued by St. Ann's Church, Montreal, the 28th May, 1898, petitioner's family name was entered as "Traghein". He alleges that this was "by mistake, error, or inadvertance" and that the family name has always been known as "Trainor" and not "Traghein". The petition was granted and the acte of civil status was ordered to be corrected.'
