Fortunately the forum on Genealogy.com's web site notified me that you had posted a reply to my message. At this time I don't know anyone who is working on the Boies genealogy (and there are several alternate spellings to that name) but I will keep my eyes and ears open. Cindy and I are working on her ancestoral line and are interested in the Boies history as well.
You may already know this, but I am confident that you can trace your Boies ancestry back to James Boies from Dublin who came to America in 1744. He had been a ship's captain and decided to remain here instead of returning to sea. He has a distinguished history and was one of the key figures in forcing the British from Boston at the time of the American revolution.
I have been trying to pin down his marriage and think that it is likely that he married either Mary Miller on 19 August 1747 or Sarah Bennet on 28 December 1752. It is possible, of course, that he married both of these women. Mary may have died (or the marriage otherwise have ended) and he remarried, the second wife being Sarah.
In any case James Boies and his wife seem to have had several children, among them a daughter who married Hugh McLean (again, there may be alternate spellings, you have the surname spelled differently in your message. Hugh McLean and his father-in-law, James Boies, were engaged in papermaking and, if fact, quite a lot is known about the paper mills in which they, and later members of the family, were involved.
Quite a lot is known about the McLean family and (although I have not found it yet) I would expect a good deal of information to be available on the descendants of James Boies since he was such a prominent figure in Massachusetts and a major heroic figure in the Revolutionary War. Since the McLean surname appears in your genealogy I think that there are possibilities in looking at these lines together.
I have a bit more information and will be tracing some of these leads further. If it seems good to you, we might keep in contact and share whatever information we find.
