I have good news for you. The ancestry of Wendell Pulver and Rachel Jager has been researched extensively by another descendant. I have been using that information as a guide and have trying to verify it and add sources. In brief, the parents of Wendell Harrison Pulver were Henrich Pulver and Helletje Muller who lived in Claverack, Columbia County,New York. Rachel Jager's parents were Jeremiah Jager (I have found various spellings: Jagger, Yauger) and Catharine Tidter (Teator, Teeter and others). The Jagers were originally from Columbia County but settled in Clifton Springs, Ontario, NY. I am happy to share and will e-mail you more information.
