All of my information on this Heinrich and his descendants comes from Brienne Leslie, my 7th cousin once removed, and she got her information about Heinrich, his son John and his son Jacob from Don Breininger.

Brienne descends from Jacobs’ son Amandus who was born in Lowhill Township in 1829 -- long after our Hartmans had left Lowhill for Luzerne and Union Counties. As an adult, Amandus too left Lowhill and settled in Perth Amboy, New Jersey where he died in 1897.
