I have completed on Ancestry the descendancy files for Samuel Gwinn Jr who married Elizabeth Taylor and Moses who married Elizabeth Wilson. They are together in one file named "A Study on Samuel Jr and Moses Gwinn". Descendants number about 1500.
Then there is the file for John Gwinn who married Sally George. It lists about 1620 descendants
Also a file for Andrew who married Mary Newsome and Ephraim who married Rachel Keller. Their descendants number 1200.
Included in these files-birth, marriage, death, cemetery and many records found online as well as old histories written about the families. Descendants of these lines welcome to join and see the information and documents, make corrections and additions.
The file on the daughters is still being worked on though I do have Ruth who married James Jarrett's portion completed. All these files are kept private to keep them free for those without Ancestry memberships and it is easy to join the files.
