Which golfing relative was runner up to Young Tom Morris when he first won the Open Championship?

Thomas Morris (20 April 1851 – 25 December 1875), known as Young Tom Morris, was a Scottish professional golfer. He is considered one of the pioneers of professional golf, and was the first young prodigy in golf history. He won four consecutive titles in the Open Championship, an unmatched feat, and did this by the age of 21.

Morris was born in St Andrews, the "Home of Golf", and died there on Christmas Day, 1875, aged 24. His father, Old Tom Morris, was the greenkeeper and professional of the St Andrews Links, and himself won four of the first eight Open Championships. Young Tom's first Open Championship win (in 1868 at age 17) made him the youngest major champion in golf history, a record which still stands.

Young Tom won the Open Championship in 1868, 1869, 1870, and 1872 (there was no Open Championship in 1871). No one else has since repeated this feat of four straight Open Championships. All four championships were played at Prestwick Golf Club, the course where he had learned golf as a youth. His 1868 win, at the age of 17, made him the youngest major champion in golf history, a record which still stands. That same year, his father finished second to him, a unique family occurrence in the Championship.
