The information for each person comes from the sources at the bottom of each page in the "sources" section. You may need to scroll down if it's off your screen. So this Nancy Freeman came from another researcher on Rootsweb. You just have to look at the source(s) and weigh the reliability.

I'll check out the additional information you mention "when I find time" :)

The pictures attached to M.Henry and to Maria White were my grandmother's. She was Arabella Henry's granddaughter. The ones under M.Henry are there based on what's written on the back of the picture, but no other information to connect them to the right people.
