Was Chelsea at the Reagan funeral? I don't think so. Even John Kennedy's daughter showed up, but Chelsea must have had a hair appointment or plastic surgery appointment so she couldn't come.
To be fair, the Nixon daughters weren't there, none of the Ford children showed up, nor did the Carter offspring. My take on Caroline Kennedy's presence was that she was representing her family, being the only one left.
Where Pres. Bush daughters there? Or all of Pres. Bush 41? All the Carter kids?
