Kirkby Town joined the Second Division of the
Lancashire Combination in 1963. In 1966–67 they won the division, and were promoted to the First Division. In 1969–70 they finished fourth, and were promoted to the
Northern Premier League. In the same season they reached the first round of the
FA Cup for the first time, but lost 6–0 at
Bangor City. However, after finishing bottom of the Northern Premier League in
1971–72, they returned to the Lancashire Combination. In 1978 the club switched to Division Two of the
Cheshire County League. They finished third in 1979–80, and were promoted to Division One. However, they were immediately relegated back to Division Two after finishing 19th. In 1982 they switched leagues again, joining the Third Division of the new
North West Counties League. They won the division at the first attempt, and were promoted to Division Two, which they also won at the first attempt, resulting in promotion to Division One for the 1986–87 season. In 1988 they changed their name to Knowsley United in an attempt to attract further support from the broader
Metropolitan Borough of Knowsley. After two-second-placed finishes, the club won the league in 1990–91 and were promoted to Division One of the Northern Premier League. In
1992–93 they finished as runners-up, and were promoted to the Premier Division. The following season they reached the first round of the FA Cup for a second time, where they lost 4–1 at home to
Carlisle United. The club folded in 1997. ==Stadium==
