Google have 403 results for Rydzikowa and 473 for Rydzikowska.
City website says opposite of Wikipedia.

However assuming name is given after second name of owner (Wojciech Rydzik) "Rydzikowa" makes more sense.
I added it into alt_name=* but I think we can switch values and make "Rydzikowa" default one (still worth to have "Rydzikowska" in alt_name).
