I tried looking into the New York archives online for you, but there are over 1400 results for that name and no real mention of dates. You can try a search of your State Archives or county records for birth certificates of your dad, it should list your grandparents name, then look for them. You should be able to find documents that record them as the parents of your father and his brother and sister. Once you get the names, there are plenty of options including web searches, different sites, and again State archives to track them down.
Sorry I can't be of more help, it's hard to look that information up without more details, which you probably shouldn't post online.
