Genealogy / Any info on the Sniatkowski surname? [3]

My father has been researching the genealogy of our family and our name Sniatkowski seems pretty rare, even in Poland. My great grandfather spelled it several ways, including Sniadkowski (his baptism papers), Sniatkowski (his draft papers and grave) and his father is spelled Schnapkowska on my great grandfather's birth certificate.

Supposedly the family came to the US from Suwalk in the 1890's.

Anybody who can provide insight into the surname would be appreciated.
