I am a descendent of Susannah through her son, John. I have a bit of info on her, as well as a genealogy line through my direct ancestors. A book I have found very helpful was written by one of our "cousins"--The author is Stephen Hawley Martin and the title of the book is "A Witch in the Family". It explained quite of bit of what was happening politically, socially, and religiously.
What else did you want to know?
I also have "google"-d her name and have found much info there about her. Please contact me if you think I could possibly help more.
