Bernard  DUMOCHEL dit LAROCHE

Québec Généalogie - What is a 'dit/dite' name?  When the first settlers came to Québec from France it was a custom to add a 'dit' nickname to the surname. The English translation of 'dit' is 'said'. The Colonists of Nouvelle France added 'dit' names as distinguishers. A settler might have wanted to differentiate their family from their siblings by taking a 'dit' name that described the locale to which they had relocated. The acquiring of a 'dit' name might also be the result of a casual adoption, whereby the person wanted to honor the family who had raised them. Another reason was also to distinguish themselves by taking as a 'dit' name the town or village in France from which they originated. This custom ended around 1900 when people began using only one name, either the 'dit' nickname or their original surname.

Bernard was a Maitre cordonnier.
The cordonnier, or shoemaker (a cordwainer in England), was a craftsman who manufactured shoes, boots, and other types of footwear. He knew how to create, with his own hands, the entire shoe from the sole to the upper. He was the cutter, fitter, designer, and polisher... Some shoemakers sold their shoes to merchants, but the majority sold their own shoes, either from their workshop or by going door-to-door selling their wares.
