A rich and prominent Texas oil family, the Hoggs, named one of their daughters "Ima." Really ~ Ima Hogg. I think there were actually two sisters with ridiculous names, but I don't rememeber the other ~ "Ura," maybe, something like that?

At any rate, as celebrity heiresses and patrons of the arts, they had to live very public lives with their silly names, and apparently never thought to petition the courts for a name change, or even to use nicknames, etc. Pretty nicely self-possessed, I'd say; maybe it's easy if you're wealthy enough...
