Pierre laPierre Funeral And Cemetery Services

On this site, it appears like it's near Buffalo, near Canada. I looked it up on the internet, because I googled a genealogy search of Rudy Giuliani and it said his mother Helen C D'avanzo was born in a place called Brooklyn, Cattaraugus, New York on this link below.

I thought it was a mistake at first, because Rudy Giuliani was born in Brooklyn (Kings), New York, and I figured what are the odds a mother and son are born in two places like seven hours apart by the same name? I've tried looking this town up on Wikipedia though and on google and nothing has come up. Is it unincorporated? Is it a division of a town?

It says it exists here too, but I can't find any information, like demography, on it.
