The reason I like Melba so much is because she was one of my villagers in Wild World, as well as one of my favorites among those villagers. In WW, I basically had a family in my town with those villagers, and I loved each one of them. When I left WW to start New Leaf, a good number of my WW villagers seemed to have followed me into my first NL town, and from that point on I felt the need to reunite with all of them.
My WW villagers were Agent S, Samson, Mallary, Rocco, Filbert, Tabby (I think), Yuka, and Melba. I also had Anchovy for a brief period of time, but I didn't like him back then. Of those, Agent S, Samson, and Anchovy were 3 of the starters in my first town. I also got Mallary from a friend and Rocco from someone on here. Yuka moved into Melemia on her own. Thanks to an awesome cycler, I got Melba yesterday. So now I just have to find Filbert and Tabby, which aren't really a priority to me anymore, but if I could at least see them again it would be awesome.
