My paternal great grandparents settled in Woodbine. The Ira Spector family came from Zaslov in 1892-94. The Samuel Eby (Ab) came from Rushanyi n 1903. I cannot tell you the criteria or the reasons why. I have the correspondences about Ira Spector 's purchase of property. The AJHM in NYC has a lot of info on Woodbine. In the Eby family their were a few real estate transactions within the family. There are also records of real estate transactions at the Cape May NJ Court House and Temple University Urban Archive that has been provided by the Greater Philadelphia Genealogical and Archival Society.
