Marie is the French version of the classic Mary. It's a very royal name with several European queens bearing the name, most famously Marie Antoinette. For some reason parents seem to enjoy using it more as a middle name than a first name, and even that has been waning in use. It's definitely not a popular name in the US, but remains widely used in Europe.
