I have personally worked with a man named Baden Powell as Christian names, also a man named Messines! Baden Powell was the founder of the scout movement and a commander in the Boer War. Messines is named for the battle of Messines Ridge in WW1. The name "Alma" which is relatively common with both boys and girls originated from the battle of Alma in the Crimean war against Russia. Likewise I have seen the word Crimea used as a girl's Christian name. The most unusual in my family in the 18th century Hieronymous, unusal not only in that it was carried by a girl usually a male name, it was grossly mis-spelt Eranamus!
