Nassau County New York Genealogy and History     This site is available for adoption! Our goal is to help you track your ancestors through time by transcribing genealogical and historical data and placing it online for the free use of all researchers. We're looking for folks who share our dedication to putting data online and are interested in helping this website become a useful research tool. If you would like to join our group and become the host of this county, please read what we're all about on our Volunteer Page and email Kim (A desire to transcribe data and basic webpage skills are necessary) Until we get a dedicated volunteer to maintain this site, we'll do the best we can to add data as we come across it. You can send your family's raw data (transcribed birth/marriage/death, cemetery, census, biography records) to us and we'll include it on this site. WE REGRET THAT WE ARE UNABLE TO DO PERSONAL RESEARCH FOR YOU. All data we come across will be added to this website, so please keep checking back.
