hi Sara,
Seen a few Quemeneur dit Laflamme in merge proposals lately, just so you know, as time passed many families opted for one name or the other when there was a dit name, so you get the original Quemeneur dit Laflamme (also written Kemner, and all sorts of weird and wonderful variations on a theme ;) ), then the children get baptized with one or the other name.
In this family's descendants I find whole sections where the name on baptisms was only recorded as Laflamme. That was then their last name at birth.
Over time some families get their original names inverted, so that what was the dit name originally gets flipped, and you see records saying something like ''Laflamme dit Quemeneur''. No rhyme or reason why, they just did. So go by original documents.
Do a search in Wikitree before creating anybody from about 1750 and earlier, there are a lot of our ancestors already there.
