William Henry Husk, A Dictionary of Music and Musicians (1900)
“ ROOKE, William Michael, son of John Rourke, a Dublin tradesman, was born in South Great George's Street, Dublin, Sept. 29, 1794. His bent for music, which displayed itself at an early age, was sternly discouraged by his father, who wished him to follow his own avocation, but before he was sixteen, he was, by his father's death, left free to follow his own inclination. He studied, almost unaided, so assiduously, that in 1813 he took to music as a profession, learned counterpoint under Dr. Cogan, a Dublin professor, and became a teacher of the violin and pianoforte. ”
