The mother’s name appears to be in heavier (bolder) pen than all the other entries, and the area behind her name seems a little fuzzy to me. This may have started out life as the BC for one of Barack Sr’s other kids, but IMHO, that’s about as close to legit as it might get.
That’s just it, I’m on the fence myself. I know to look for things like pixellation but beyond that I’m pretty much stumped.
I still can’t get her on the phone, which is the part that’s annoying me.
