The simple question is what is a "dit name"?The story I post around follows: We were in Quebec on vacation about 10 years ago and were treated like celebrities because the only LaFleur most people had heard of was Guy LaFleur, the famous hockey player.There were no LaFleur's in phone book in Hull where we stayed most of the time.(I just now found 6 listings by internet search in Hull and only 250 for all of Quebec)
We visited an heraldry shop in Montreal; the first clerk came up dry on the name LaFleur but as we were leaving the manager came in; she found LaFleur under "dit birot" so we bought a "family crest" that gave somebody somewhere the name "La Fleur dit birot."
I have found no explanation for the "dit birot."Since the crest contained an magen david, I am assuming a Jewish connection so it could even be some corruption of Hebrew or Yiddish as well as French, German, Flemish or Dutch.The rest of the crest was a bear claw and a diagonal bar of three roses.
