In 1914 she won the first of her four
British Ladies Amateurs, taking the title from
Muriel Dodd. Her opportunity to possibly win several more was interrupted for five years during
World War I. When the Championship was restarted after the war, she won her second straight title then the following year made it three in a row. Leitch was able to reach the Championship finals on six occasions, and in 1926 won her fourth British title, a record she shares with
Joyce Wethered. She received golf lessons from
Thomas Renouf, the head professional at Silloth. Leitch retired from competition in 1928 having won 12 UK national titles, plus five
French Ladies Amateurs and one
Canadian Women's Amateur. Leitch was a regular writer on golf for newspapers and magazines, and published three books on golf:
Golf for Girls (1911),
Golf (1922), and
Golf Simplified (1924). ==Later life==
