[Ger-Poland-Volhynia] Meaning of "ow" name ending in Polish.

[Miles Ertman]

Hello,

I am wondering what the "ow" attachment to the end of a surname means in
Polish.  For example, I have a marriage record from Plock, Poland which
states that Floryan Schmidt married Dorota Schmidtow.  Does the "ow" ending
in Schmidtow mean that Dorota's maiden name was Schmidt?  i.e. Does it mean
Dorota nee Schmidt.

Thanks,
