Charles Clegg was the son of Mary and William Johnson Clegg, who went on to have a total of six children. His father was a trainee solicitor at the time of Charles' birth. Two years later he became a highway rate collector but re-entered the profession after the
Great Sheffield Flood in 1864. He prepared claims against the water company responsible. This led to him to become a fully qualified solicitor and found his own firm, which became known as Clegg & Sons. He also went on to be
mayor of Sheffield three times. Charles joined his father's law firm after leaving school and eventually became a solicitor in 1872. In the same year, he married Mary Sykes, with whom he had three children. Both Charles and his brother were noted athletes with a flair for football. Charles was also an outstanding runner winning prizes at the 100 yards sprint and the quarter-mile. Locally he played for
Sheffield F.C., Perseverance and Broomhill but his favoured club became Sheffield Wednesday. He and his brother represented the
Sheffield Association in the first inter-association match against the FA at
Bramall Lane on 2 December 1871. The game was won 3–1 by Sheffield, and Clegg became a regular feature in inter-association matches. The highlight of his career came when he represented
England in the
first international played on 30 November 1872. However, he did not enjoy the experience later stating that his teammates were 'snobs from the south who had no use for a lawyer from Sheffield'. This proved to be the only cap that he earned. He and William went on to become the first brothers to win English caps when his brother earned his first cap the next year. In the
Football Annual of 1875 by
Charles W. Alcock, he was described as "very fast with the ball, passing it with great judgment and, when within sight of the enemy's goal-posts, an unerring kick." Towards the end of his career he earned one last distinction. When it was decided to experiment with the first floodlit match he and his brother were chosen to captain the two sides involved. On the night of 15 October 1878 a crowd of 20,000 turned up at Bramall Lane to see the Reds (captained by Clegg) beaten by the Blues 2–0. The game was declared a huge success. ==Rise to the top==
