Hi Celina,
I do not help you, but I give you very interseting information.
Rytarowski - it is very rare in Poland, old, noble surname.
In 1990 only 26 Rytarowski 's lived in Poland and I think, that all Rytarowski's in world are related.
Surname Rytarowski first time was noted in 1444 [also spelled as Rejtarowski, Rytarowski] , coat of arms Topor.
