I agree. "Something" would be nice. If we could have the name on the profile and tree in bold that would work. The bold option could be used for indicating the direct ancestors or it could be a flag to the tree owner that this individual has some unverified information that needs to be resolved. Perhaps having an italic option would also be helpful. I have started writing dates, places in lower case to let be know that I have some reason to suspect them. (3 jan 1822 or tacoma, piece, washington). These suggestions have drawbacks, but I put them out as part of a brainstorming process. Perhaps they might trigger a better idea from someone else.
