Names In Trend: Ends In "O"

Fun. Youthful. Spunky. That's what I associate with most names that end in the "oh" sound. Parents also seem to agree, with several of these names climbing up the charts, and others becoming trendy in Hollywood. Most of the names that end in "o" are predominantely male, since a lot of them are from latin origin.

"Oh" ending names that are on the rise include:

Alejandro (#102) - Lady Gaga influence perhaps?
Santiago (#133)
Leo (#193)
Mateo (#221)

Emiliano (#241) - maybe people want a fresh male version of Emily?
Romeo (#358) - surely the Beckhams are behind this one
Beau (#375) - another Spice boy
Rocco (#392)
Milo (#422) - used recently by actress Alyssa Milano
Matteo (#428) - trending faster than the other version
Enzo (#443)
Maximiliano (#468) - I guess Max is a nickname everyone is after
Aldo (#512)
Carmelo (#777)
Theo (#915)
