Are you aware of the following publication?

Johannes Heintz and His Descendants by John Clagett Proctor?

This covers Johannes Heintz from arrival, and has quite a bit on the Heintz/Hines who remained in the MD/DC area as well as the group who moved to Harrison County, OH. I've found some errors, but all in all, it has a lot of info to work from.

I have a copy from the Higginson Book Co. www.higginsonbooks.com
