History of the name "Philip" (one "L")

King Philip the Second of Macedonia

 Philip

A short form of Philip—derived from the Ancient Greek Phílippos—Phil shares a claim to its components philos, meaning "love," and hippos, meaning "horses." Philip has been revered since antiquity, bestowed upon many Macedonian kings, including the father of Alexander the Great.

(Note that the original spelling in Greek only has ONE "L" in the name.)

All of this information was culled from many websites found by typing "Philip" into Google Search. None of this information was researched or authored by myself. These are not my words, only my own layout.
