Liv combines the succinct charm of a nickname—people might assume it's short for Olivia—with the solidity of being a classic stand-alone Scandinavian name with a life-force meaning. It was brought into the public eye (in the English speaking world that is) due to the fame of actress and Aerosmith daughter Liv Tyler.

Popular Scandinavian name -- first bestowed in honor of Swedish botanist Carl von Linné, a classifier of plants and animals -- that could make an engaging choice.
