If you go back far enough in Quebecer geaeology, the tree has few branches. Aren't Quebecers with the same last name all related back to the same French colonial families?

"Aren't Quebecers with the same last name all related back to the same French colonial families?"

Likely true in a general sense; barring duplication of surnames, subsequent French immigration; long institutionalized spelling errors, etc.

Plus, there's the whole quasi-racist 'pur laine' status thing in Nationalist circles with a lot claiming they can trace their ancestry back to ol 'Jean-Guy Rubberboot' in the 1600's with his own personal Royale-bestowed Seigneury on the banks of the St. Lawrence when, in reality, considerably few of them likely can.

There's been plenty of French-Canadian outside intermarriage over the years too:
Not so much with the English but with the Irish and especially with the Scots. It's not all that uncommon to find denizens of la belle province with a really Scottish name whose mother tongue is now French (e.g. Robert Burns - the Pequistes Legislative House Leader back in the 70-80's).
There's also been more intermingling 'avec les maudit savages' than many Quebecois would like to admit with such ancestry being viewed in more than a few quarters not unlike one having a remote Jewish background 'taint' is by some in old Europe.
