I'm a descendant of Charles Foster a.k.a. Karl Foerster, a Hessian soldier who emigrated to New Brunswick, Canada, after the Revolutionary War. He married a Catharine Lounsbury in 1796, and had ten children, including Daniel, Thomas, and my ancestress, Martha (proven via DNA testing). I started a group on Facebook for his descendants - if any other descendants are interesting in joining, send me a private message and I'll send you the link.
