Ghanaians are given a name corresponding to the day of the week that they were born on. I was born on Wednesday, so this is mine. I'm not sure what they do with twins exactly...maybe Brie would have the same name. Big Mama did seem to indicate that all her daughters were named Melody (maybe it's just not a big deal, kinda like George Foreman and his kids).
However, when I was riding with my taxi driver someone yelled something to me and I've gotten in the habit of asking him what they're saying (it's usually in Ga). He said they called out a name, maybe it was a nickname he gave me (I go the same route a couple times a day). The weird thing was, he said the name means "firstborn twin." And then he told me what second-born twin was. I told him I was a firstborn twin, and he laughed.
