My father was church choir-master at Watchet in Somerset, his mother taught several vocal soloists in Liverpool and his brother was a baritone soloist.
My mother was a choral singer and her mother and aunt were both church organists. I have been told that my great-granfather on that side played concertina, but don't know what type.
I don't know much about anyone further back than that except I am told that someone who researched the family tree found a court musician back in the 1700s.
