Delaunay might get lost in web searches for you specifically. Majority of people can not type, less can spell correctly or auto-correct will mess it up.
Uh...in relation to a last name for me?...I can't really be known as Danielle FTV on other websites or movies and I don't want to be just known as Danielle. I think Jones has an all American girl feel to it but Delaunay is beautiful and exotic sounding. BTW Delaunay pronounced dee-lawn-a ("a" as in bake). It's also the last name of my favorite book character.
