Born in Lascelles Hall, Huddersfield, Yorkshire, England, Lockwood was the nephew of John Thewlis senior, who also played for Yorkshire from 1862 to 1875, and the brother of Ephraim Lockwood, who played from 1868 to 1884, and was related to the cricketing Eastwood and Bates families who also lived at Lascelles Hall. By no means as talented as Ephriam, he was a good league professional, being engaged in 1879 at Hollen Hall, Oldham and at Rochdale C.C. from 1884 to 1886.
