Fleur Delacour
Fleur attended as Bill's girlfriend. This was the first time she'd been around any of his family with this title, and she wore it with pride. She remembered most of his siblings and tried to talk with some of them (though wasn't always accurate with the names, especially where the twins were concerned, and I'm sure they didn't help matters). This was also the first time she met Bill's parents, so she did her best to make a good impression in the only way she knows how: being a little haughty and proper. She would have special congratulations for Ginny (I think this would be the first time they've spoken properly?) and would insist that they get to know one another better.
