Very interesting article, Mary. But in reference to your initial dilemma, there are 40 individuals listed on the page, 22 males and 18 females. In the summary at the bottom of the page, it records 22 males and 18 femals all white, zero coloreds. So, unless the mulattos were grouped with the whites rather than coloreds, which I regard as improbable, the "M"s are all actually misinterpreted "W"s.
