The oldest (after a career in education) became the church organist in her retirement years. The other 2 daughters had lifelong careers as music teachers. I don't know about the sons -- one played the violin all his life, but made his living as a chemist.
My father managed to learn to play enough piano (his assigned instrument was cornet) to impress my mother enough to marry him! BTW, he was taught the little bit of piano he did know (a very impressive rendition of the first page of The Swan) by his sister who actually was a cellist. Surely that was an imposition on her free time as a teen when she could have been out "having fun". s/off!
