It appears that you are trying to add ancestors for George, and that his profile manager has not been active for the past year. It also appears that George is set to orange (is it orange?) so that you can't currently add your ancestors. Given that there is an unresponsive PM procedure, you probably want to begin with that. In the meantime, were it me, I'd find sources for a your great-grandparents and politely post this info in the comment box for your grandfather's profile thus giving this manager the info he might be able to add himself and hopefully make you a co-manager as he does so. Remember he will need your email address to add you. (Some people seem quite possessive of "their" profiles.)
