For those familiar with the solutrian migration theory the Lumbee population might represent a population of people descended from original ice-age migrants who made it here from Europe around 50,000 years ago.

Sounds like a lot of hooey. Even if some visitors did report Indians with white ancestry (a lot of which are hoaxes, like the fairy-tale of the Welsh-speaking Indian tribe propagated by Morgan Jones) these all came well after European explorers had reached North American shores, and hence require no explanation other than a sailor's layover.
