How very strange you are looking for both these surnames and there is even one more coincidence:
Stanislawa Karpinska married Franciszek Cichy
Rosalia Karpinski (sister to above) married Kaczmarek.
Both families came from the area north west (i.e. Blizanow) and also north east (i.e. Borkow) of Kalisz city (Poland).
Both these surnames are very common to the two areas mentioned - I have just come back from them (Poland).
