I do have a tree posted on Ancestry as well, but I do keep it private. I'd be happy to give you access if you want to give me your Ancestry user name or send me a private e-mail. And I'd love to fill in George's descendant into my tree.
I do have some more recent information and need to update my family tree online. As you probably gleaned from the notes on the site, George's father Frederick was illegitimate. I have been talking further with Robert Spencer, a great-grandson of Frederick, and he advises that he can confirm Frederick's father as Thomas Cail, as told to him by Babe Walker, a niece of Frederick, and it was Frederick's mother, Janet Thurrott, who told her. So, that story pretty much resolved. One other way to absolutely confirm, is if you have a Thurrott male in your family who would be willing to do a yDNA test. Since that test confirms a son of a son of a son solely through the male line, if the results came back as matching Cail's, you would know for sure.
On the Thurrott side, Robert has been working very diligently to prove the earlier lines, and I think he's come up with some interesting info. While still not 100% since there are gaps proving the first wife of John Thurrott who came over from Scotland, it would certainly seem that John is a descendant of Francois Thurot, a famous Manx smuggler. One his starting points, was that Babe Walker has also told him that there was some association with the Thurrotts and Castle Douglas in Scotland. I hope Robert doesn't mind me sharing this...but here are some of his research notes:
John Thurot b. 1755 Kirkbean, was raised at Castle Douglas, Dumfries. At the time of the death and burial of Francois Thurot, Lord Maxwell who presided over Francois Thurot's funeral, buried him with full honours in the churchyard of Kirkmaiden, at the expense of the local lord, Sir William Maxwell, who also served as chief mourner. He directed that his servant travel to Castle Douglas to deliver the watch of Francois Thurot to his son and heir. Lord Maxwell, later continued to assist the same John Thurot. In fact, the son of Lord Maxwell, Mungo Maxwell, having taken up the trade of carpenter and who was a good friend of John Thurot, served on the same ship going to Tobago with John Thurot under the command of none other than John Paul Jones, who was acquainted with John Thurot as they were both born at Kirkbean. During this voyage , the Carpenter Mungo Maxwell was cruelly flogged, upon returning to Scotland, young Thurot, only 15 at the time, told the story to Lord Maxwell, who had John Paul Jones arrested and tried in court. John Thurot testified at court.
