Rosario

Rosario is a sans-serif typeface designed by Omnibus-Type, added to Google Fonts in 2011. It's available in 5 weights, as a variable font.

This is one of 3 character sets supported (latin, latin-ext, vietnamese). Being free and open source, it's a great choice for web projects, print, and branding — and it's a frequent result in the font finder.
