Does anyone know anything of John Anthony Dunbar b: c1900 in Jamaica who was a musician in London in the 1930s. He fathered a child with Gladys Constance Price formerly Brennan in 1934 - I have the birth certificate. They lived at 1 Peter St, W1. I am looking for anything to expand my knowledge of him but obviously more particularly his parents and birthplace in Jamaica.
Thanks and best regards - David Webb
