Q for American users: do you still have your original family name?

[Jägerstaffel]

Sure do.

[MysteriousWays]

It was changed, but not dramatically in my case.

[Bobby Martnen]

Kowalski could also become Kovalsky.

Or even Covalskey, if you really wanted to rewrite it in a more English-looking way. (instead of just phonetically)

After all, Americans turned Myszkiewicz into Miscavige.

[Bobby Martnen]

It was changed, but not substantially (end chopped off).

I guess you could say that your surname got circumcised lol

[Bobby Martnen]

I do, albeit with a very minor spelling change.
