Vickie,
What are the Carleton Papers and Dorchester Papers? I'm unaware of those...can you fill me in, please?
Sutherland, in "Hessians in Annapolis County," states "2 persons" for J.C. I had believed he received the larger tract of 400 acres due to his elevated status in the regiment. Some Hessians were allowed to bring families - wives and children, with them to the US. J.C. arrrived with the Ansbach-Bayreuth Regt. in 1777. I have never seen a reference to him bringing a family with him or having been married prior to the citation by Dohla. Of course, that doesn't mean it didn't exist, but I'm not under the impression that he had a wife and children to think about while he was a POW in Frederick.
Dohla's diary, as well as some others, were compiled after the fact, sometimes noting later situations and it's difficult to pin them on the timeline.
