Would be nice if anybody could figure out the character name.

First name seems to be Stella but I'm not so sure what her surname should be.

I believe it should be Braemer. She's listed as Swedish, and Google reveals that the chairman of the Swedish-American Chamber of Commerce in San Diego is one Christian Nielsen Braemer.
