Background
William was born on January 31, 1854 in Lyons, New York, United States, the eldest of seven children of the Rev. Lyman Hinsdale and Mary (Balis) Sherwood. On his father's side he was descended from Thomas Sherwood, who emigrated from London to Ipswich, Massachussets, in 1634, and settled in Fairfax, Connecticut, and on his mother's side from John Balis, a farmer with a large grant of land between Cairo and Catskill, New York. Lyman Sherwood was a man of culture, an accomplished linguist, an excellent pianist and organist. He supported his family by teaching music, being so successful that he founded Lyons Musical Academy in 1854, the second music school founded in America.
William Sherwood showed musical talent at the age of four.
