In 1949, after a number of particularly lean years, Crosserlough Gaels was reorganised under the chairmanship of Pat Reilly, Druninisclin. The first championship cup to come to the parish was won by Crosserlough minors in 1954. This was a brilliant fifteen and included John Byers, Jimmy Smith, Donal Crotty, and Philip Maguire, all of whom were to play a very important role in Crosserlough's rise to the top. The master tactician, Brian Beglin, ably assited by Kevin Boylan and Peter Byrd, tutored the team. 1955 was equally successful and the minors repeated their performance of the previous year. This resulted in the County Board passing a bye-law to curb Mr. Beglin's activities. It was a winning streak that continued into 1955 when, under the chairmanship of Tom Dowd, Crosserlough won the junior league.

Growing confidence was in the air in 1958. The previous year  Cootehill knocked Crosserlough Gaels out of the championship. Despite winning everywhere except on the scoreboard, Cootehill beat them by just one point. Although it was a defeat, it was one that was tinged with hope as it indicated that Cootehill supremacy was in decline. Leaving nothing to chance, Crosserlough management asked Peter Donohue, who had left to play with Mountnugent in 1945, to return to the fold. He obliged. Crosserlough was also showing signs of maturity in the senior league. The 1957 competition had continued into 1958. Crosserlough met Balieborough in the final and defeated them by a winning margin of 5-8 to 1-2. The same teams met in the championship semifinal, where Bailieborough's attempts to regain face failed. Cavan Gales defeated Cootehill in the other semi final. The stage was set for a record breaking final! Conditions were ideal.

The thirty-strong squad had trained as many as five nights a week, and virtually every man, woman, and child in Crosserlough was there to voice support. Nothing less than victory would satisfy them. It didn't start well for Crosserlough. Just two minutes in and Cavan Gaels were two goals up! After fifteen minutes of play, Cavan were nine points ahead. A great fighting spirit and an all-round ability, plus the craft of Noel O'Reilly, Hubert Gaffney, Brian O'Reilly, Gerry Duffy, John Byers, Peter Donohoe, Sean Lynch and Jimmy Smith was not to be denied. Three minutes from the end and all was square. Crosserlough's winning score was a goal from Jimmy Smith, the ace forward. The Crosserlough team was the new champions by a score of 3-7 to 3-4. After all those weary years, the Plunkett Cup reached Kilnaleck, to be met by brightly blazing bonfires! Crosserlough were odds-on favourites to retain the championship in 1959. It took a replay against Cavan Gaels to secure victory in the semi-final and they met Virginia, for what was viewed by many as a mere formality. However, in the dying minutes of the game, Virginia stole the victory. There was some solace in the fact that Crosserlough retained the senior league. 1960 was a fruitless year, but Crosserlough was back on target in 1961. They regained the championship by defeating Ballinagh by 2-8 to 2-3.

In 1963, Benny Boylan's schoolboys won the County Cavan Championship (rural area) for the first time. They repeated the performance in 1964 – ensuring a steady stream of talent for the Senior and Junior titles for the coming years. The Senior Team won the senior league and the minors won the minor championships in both 1963 and 1964. They all retained their trophies in 1964. In 1965, the seniors won another senior league title. 1966 was equally victorious with the formidable Crosserlough team deafeating a shocked Ballyconnell by a score of 3-13 to nil – despite it being one of the worst county finals in living memory! 1967 Was one of the greatest years for football in Crosserlough. Never before had one team won the senior and junior championship on the same year and at the same time contested the minor final. In a repeat of the 1958 final, Crosserlough met Cavan Gaels. The opposition, playing fast, clever, constructive football, dominated the opening period. At half-time, the score was 3-4 to 0-7. Not to be beated, the Crosserlough men called on their reserves of fitness and experience, and overhauled their rivals by four points (Crosserlough: 18 pts, Cavan Gaels: 3-5). This was a remarkable victory, demonstrating that courage and fitness will always triumph! Crosserlough supporters were still celebrating when the junior side stepped onto to soil of Breffni park to contest the junior final. Even though the team lost a number of players to senior ranks in transit, they proved, by the way they defeated Belturbet in that final, that ‘the lough' was bristling with talent! This marked the first occasion for the junior championship cup to come to Crosserlough

The stage was now set for Crosserlough to embark on a championship-winning streak, which is second to none in the county. Seven senior titles in a row were won between 1966 and 1972 and for good measure the club also won the Junior Championship in 1967. Since these glory years success at senior level has eluded the Kilnaleck club but nevertheless a steady stream of silverware has continued to flow the way of the club. Numerous schoolboy titles have been won along with Minor titles in ’86 ’88 ’89 and ’95, U-21 titles in 1983 and 1984 and Junior B titles in 1997 and 1998.

Side by side with the men we also boast a very successful camogie team. Founded in 1982-success came instantly with the girls winning the Intermediate League. In 1984 the club had success in the Novice Camogie League. 1990 saw the club reign as U-14 champions and this was added to in 1992 by the Junior A team who brought the cup to Kilnaleck. Building on this the Intermediate title followed the next year and in 1996 the senior league trophy resided in Kilnaleck. Crosserlough were crowned Senior Champions in 1999 and this team done the club proud by reaching the Ulster Club Final where they were narrowly defeated.
