I live in Butler County Pennsylvania where the Vanderlin family settled after moving west from Chester County. Nicholas Vanderlin had a grandson Stephen. His gravemarker still stands in Venango County. Stephen had a son Joseph who was a prominent attorney in Butler. Joseph had a son Samuel who is my great grandfather. My grandmother was Mary Vanderlin Iman. The Vanderlin family was very prominent in the Butler area. If you go back through the old newspapers you can learn lots about the family. Also from what I have learned the surname was originally Vanderlinden and shortened to Vanderlin.
