Hi Janet: All land records prior to consolidation of Queens into NYC and the subdivision of Nassau County, from Queens, in 1899 are in Queens. The basement also holds an unbelievable collection of antique maps as well as the original grantor/grantee indexes. Today this is under the jurisdiction of the Department of Finance of NYC and their website is: http://nyc.gov/html/dof/ The individual borough offices are listed at: http://nyc.gov/html/dof/html/email.html#register The most popular commercially produced maps are the 1873 Beers maps, which is a bit later than the period you are looking for. Another resource that you might find helpful in the map area is the Clerk's Office for the Town of Hempstead. They will not have land records themselves but their archived collection of Town papers is amazing and indexed online at: http://www.townofhempstead.org/ Besides land records, you may find mention of your ancestor in the Town Records. Many deeds and mortgages were recorded at the Town Level (as Town Meeting minutes and other records) as well as the county level. What is the name of your ancestor and what, specific, time period(s) are you looking for? Good luck and best regards. Nancy.
