Orville – Old man names are coming back into style – just look at Oscar. Orville could be the next old-school O baby name that enters the top 100. Orville means “gold town”.

Orson – Another old-school option, Orson means “bear cub”.

Ovette – A combination of Yvette and Odette, Ovette is a name many haven’t heard of before. Cute yet classy with a vintage feel, Ovette could be a winner.
