Katherine Rosaleen Mills was born in 31 South Square, Inchicore, Dublin, on 8 October 1923 to a Dublin mother and a Cork father. When she was just eighteen months old her mother died, leaving her to be raised by her maternal grandmother. Her father worked in the Inchicore works and therefore Kathleen was able to participate in and avail of the sporting activities in the Graduate Student Researcher Athletic Union.
She was educated in the local convent school at Goldenbridge, where she played table tennis and soccer as well as doing gymnastics.
She is regarded as one of the greatest players of all-time, winning a record 15 All Ireland Senior Medals "that no other player in Camogie, hurling or football has equalled." From a young age Mills showed a great interest in a wide range of sport. However, camogie was her first love. Two pence per week were deducted from the worker’s wages to go towards the financing of the sports activities in the Railway.
In 1947, Mills married George Hill.
Mills made her camogie debut with the Great Southern Railways club in Dublin in 1938 at the age of 14, and was promoted to the senior team for her second match. Three years later in 1941 she made her debut for Dublin while still 16 and played in Dublin"s unsuccessful All-Ireland final against Cork, winning her first All-Ireland medal after a replay against Cork a year later.
In 1943 the same counties met in the All-Ireland final for the third year in-a-row. Once again Mills ended up claiming an All-Ireland medal, her goal from fifty yards range being described as the highlight of the match.
The following year, 1944, brought a third All-Ireland medal.
In 1945 and 1946 a dispute in the camogie association kept Dublin out of the All-Ireland championship in spite of being Leinster champions in both years. In 1948 Dublin were back on form and Mills captured a fourth All-Ireland medal. She took no part in the 1949 championship, however, the 1950s would bring much success to Mills.
Between 1950 and 1955 (inclusive), Mills captured six All-Ireland titles in-a-row.
In 1956 “the Dubs” surrendered their crown to Anrtim but it was soon reclaimed in 1957. In 1958 Mills was appointed captain of the Dublin camogie team
Led by her, Dublin defeated Tipperary to capture yet another All-Ireland title. She captured three more Allin 1959, 1960 and 1961.
The occasion of the 1961 final was special as it was Mills" 38th birthday and her last outing in a Dublin jersey.
In her playing days Mills was regarded as one of the all-time greats. In retirement this opinion of her grew. As camogie’s first superstar she has often been described as the Christy Ring, Mick Mackey, Nicky Rackard and Lory Meagher of the camogie world.
With a record haul of 15 senior All-, Mills remains the most decorated player in the history of Gaelic games.
Kathleen Mills-Hill died on 11 August 1996 from undisclosed causes, aged 72. In 2010 the camogie trophy for the annual inter-county All Ireland Championship for counties graded Junior was named in her honour.
