I can't thank Judy enough. Her blog is one of the best in the genealogy & family history space, and sets a high bar of others to follow. She didn't have to take the time to answer my question so thoroughly, but she did, and I am grateful. This is another example of the wonderful genealogy community.
I copied the image she found signed by Manuel Lamon from the Revolutionary War pension file of Catherine Acre, widow of Philip Acre (widow's pension application number W.9690).
So now I have some additional ideas of where to look for information. Unfortunately, some of these will have to wait on my research wish list.
