Horatio is my all-time favorite name...and I mean that. I was about 4 when I first heard it. I get very happy when I see that people are using it! :) I don't know why
Horace is still more common.
Some of the other names on this list are awesome too though.
Ptolemy Douglas Austin?!
Ludovic Henry Nicholas Raphael? Epaminondas
George?
Lavinia Anne Philippa Fox?
Cosima Caroline Heather? Wulfstan?
Cleopatra? I've just gone squee.
On a more serious note, why are there two Tarkas, and where does that name come from? Also, why are there so many children with three middle names? I didn't think it was common to have any more than two.
