Several Philadelphia's, a couple of Charity's, a Hope, an Esau, a Staning, one or two Barbary's, quite a few Lettice's, a Grace Contalmaison (named after a WW1 battle), a Hamelton, a Goddard, and a Pierce are the most unusual first names in my tree.
I still like the name Philadelphia Pennyfold from my tree the most. Sounds Dickension to me
