Hi there - I'm the one who posted the original info from documents found at Footnote.com - now FOLD3. As I stated there were over 90 pages of documents. It was some time back when I posted Alexander Ritchie, Jr.'s -among many others- but generally I gleaned the most important info from those documents - HOWEVER - I may have missed something ! I believe Fold3 has a free trial & you may want to take advantage of it. Afraid I can't help with any other info.
All my best,
