Milo
Meaning
soldier, merciful
The story
Milo's etymology is genuinely unsettled, and the honest answer is that it has more than one plausible parent. It may come from the Germanic element behind mild and merciful, or from the Latin miles, soldier, or from a Slavic root meaning dear. Good sources disagree, so we hedge rather than pick. What is not in doubt is the curve. Milo ran to about 1,700 babies in the 1920s, eased down through the middle of the century to about 500 a decade by the 1960s, and then turned sharply: 3,300 in the 2000s, 14,000 in the 2010s, and nearly 18,000 so far this decade. Our own data also files it among cat names and dog names, which is not the insult it sounds like. Names that read as warm, short and slightly old fashioned tend to land in both places at once, and Milo has been doing exactly that for a while.
