The Ostrander Family Association (OFA), founded in 1984, has continuously worked with our members in the effort to support research and historical documentation related to the Ostrander surname. For many years, the Ostrander “Big Book” has provided members with the most comprehensive repository of Ostrander genealogical data. We strive to continue this legacy as we move to embrace the next generation of genealogical research, with online searches and genetic results and comparisons.
