I realize that this thread is old, but I have Drapers in my tree going back through the 1700s in Rushden Herts, and before that in Cottered. The Edward Draper mentioned in one of the posts is, I think, my Great Great Grandfather, who moved to Northfleet around 1875.. His son George Joseph is my Great Grandfather and my Grandfather was his son Hardy George Alfred Draper.
If you are still monitoring this I'd love to swap notes
