Mary Ramsey (born 24 December 1963), a resident of Buffalo, New York, is a member of folk rock duo John & Mary and lead singer and violinist for the American alternative rock band 10,000 Maniacs. Ramsey has also worked with other well-known artists such as Jackson Browne, Goo Goo Dolls, Billy Bragg, Warren Zevon, Alex Chilton and Ani DiFranco. Using only the above description and what you know about the world, "Mary and John, the duo members, are married." is definitely correct, incorrect, or inconclusive?
