Actually, I'd say English claims the title of being the truest descendant of Latin. English not only directly uses descendants of Latin vocabulary, it also uses plenty of words from the other Latin descendants. It's kind of like a C++ diamond inheritance pattern.
English actually comes from West Germanic (not Latin). But you're right; there are lots of shared words between Latin and English, and this is mostly due to the historical relationship between England and France.
