I am trying to find out any information that I can on Isaac Hagerman. I have a few of my dad's notes that said Isaac came from New Jersey. My dad's notes also say Isaac's father was Hendricus Hagerman/Hegeman. But I cannot find anything concrete about either one of them. I have no idea when or where Hendricus was born or if that is even his correct name. Isaac's mother is also a great mystery. If anyone has run across anything that sounds remotely like any one of these people, please give me a shout. It would be much appreciated.
