Not in this case, Valkenburg is a apparently a town in the Netherlands. She also has the Dutch "van" in her name (which means "from") so her name is basically "Chelsea from Valkenburg"). I guess she has Dutch heritage? Not sure.
She's not Jewish, and don't forget that many non-Jew names end in "berg", as you will often find such names in Scandinavia and Iceland.
It's the German (((berg))) that you need to watch out for.
