Daynes, Joseph
From New York City LDS History
From article on the Daynes Music family in Utah at The Whole Year Through: Daynes Music advertising, 1915.
"The John Daynes family made an early mark on Deseret�s music culture. John�s son Joseph, age 11, was already proficient on the organ when he first played for Brigham Young in 1862. Following training in New York City, he became the first Tabernacle organist at age 16."
