Is there a town called Brooklyn in Cattaraugus County, New York?
In this http://www.roadsidethoughts.com/ny/brooklyn-xx-cattaraugus-nearby.htm site, it seems as if near Buffalo, near Canada. I looked on the Internet, because a google search and genealogy of Rudy Giuliani said his mother Helen C D'Avanzo, was born in a place called Brooklyn, Cattaraugus, New York, on the link below. I thought http://www.gedview.com/giuliani/pedigree.php?rootid=I1 it was a mistake at first, because Rudy Giuliani was born in Brooklyn (Kings), New York, and I figured what are the odds of a mother and her child is born in two places as seven hours of difference with the same name? I tried to find these people even in Wikipedia, and even on google and nothing has come up. Is it unincorporated? Is it a division of a city? Http: / / www.brooklyn.net/other_bklyns/other_bklyns_02.html is said to exist here too, but I can find no information as demography, in it.
Apparently so, but is listed as a village in East Otto. Http: / / en.wikipedia.org / wiki / East_Otto, _New_York # Communities_and_locations_in_East_Otto
