Absolutely ask away! - It's why I posted the book. :)
I wish it listed parents, but only on very rare occassions does it include even the father's name. The only extra information it lists is Bondsman or Minister. In the case of William and Martha the Bondsman was Freeman Winn. A Freeman J Winn was also the Bondsman in 1846 for a Rebecca Winn. Of the numerous Winn marriages, those are the only two where Freeman Winn is the bondsman, which may or may not be significant to you.
Although now that I look more closely there were at least 2 Freeman Winns in Lunenburg County during this time.
