Breslau Cemetary still sits in the center of Lindenhurst off of Sunrise Highway. It still has vacancies and I have noticed many children are buried there due to the lack of restrictions on decorating the graves.
LI had more than a few German-towns. New Hyde Park still has a couple of dozen octogenarian Germans holding on to the houses they bought in the 40s. And, I am currently working on a script entitled "Polishtown" set in Riverhead and the Hamptons.
