There was Richard Wood and Richard Woods of Albemarle. Richard Woods married the daughter of Richard Woods of Augusta--Augusta County records. I agree there is much confusion with the tendency of the records clerks to add and subtract "s's" without much sense to it. Bear in mind there was also a second Joseph Woods with an "s" further west, also. The Wood family of Albemarle and adjacent areas is another family with which I'm also familiar. I've done a family history for a probable cousin of yours out here, and I have the same family connected with my Wallace line through the sister of one of my more recent ancestors. I spent a considerable amount of time sorting out Joseph's and Richards. Trust me there were three Richards: one Richard Woods of Albemarle, merchant and planter whose wife was Elizabeth Woods and whose father-in-law was Richard Woods of Augusta-Botetourt, and a Richard Wood of Albemarle. Another cousin wondered if his Joseph Woods of North Carolina was connected to the Josephs of Virginia and I spent some time on the Joseph Wood and Joseph Woods as well. (No, he wasn't connected to either--his line of Woods never passed through Virginia...)
I hope this helps some.
