I've got the same pieces of paper! However, I was able to find something interesting about (Sir) Simon Stuart. He must have been some kind of forebear, but I can't make the connection yet.
Anyway, what I found was from a magazine whose name I forget for the moment. The publication, which existed for about 40 - 50 years in the early 1700s, is actually available online. Or it was a few years ago when I found the reference to Sir Simon Stuart.
There was a small article, no more than a paragraph or so, which told that he had been lucky enough to find a treasure trove of gold coins buried on his land by his grandfather during the English Civil War.
I'll try to dig it out in a few days and give you specifics.
