Surnames ending in man/mann

[Augustus27]

I guess I'm just trying to provoke a thoughtful discussion here.

It's common knowledge that surnames ending in mann are German, where as surnames ending in man are usually non-German (English, Turkish, etc). In the New World many surnames were Americanized and many German surnames ending in mann were changed to man, just dropping the second n. So the thing is, are most surnames ending in man in the New World, are of German descent (Americanized) or of non-English descent. Now, I know some surnames ending in man aren't German, (Truman, Hartman), but it would look like most are German.

I will apologize for bringing up this frivolous topic, but it snowed a lot and I'm bored :p.

Also common in Jewish surnames.

I did forget about Jewish surnames, mainly Ashkenazi. Most Ashkenazi surnames are arguably mainly of German origin.

Ashkenazi surnames can end with both mann or man, but the latter is probably more common nowadays. I don't think most Ashkenazi surnames are of German origin - Polish and Russian names are probably equally common.
