By 1930 the membership had expanded to include over fifty players turning out in the club’s strip of the time which was a blue shirt with an emblazoned white star.
The recently excavated sand pit there was made available and an enormous effort on the part of its members turned it into a playing field.
On the team sheets the names of Freddie Spencer, Malcolm O’Grady, Jack McDowell, Billy Campbell and Paddy Lavery regularly appeared.
Under the captaincy of Jack McDowell the 1st XV were the beaten finalists in the Minor (nowadays referred to as Junior 2) League for the 1932/33 season.
His ambition for the Club was achieving the impossible dream, winning the Metropolitan Cup (competed for annually by Dublin’s Junior 1 teams).
The 'Met Cup' had come to Sutton in fulfilment of a dream conceived by Seamus Henry and realised with the efforts of players like Tom Geary, Brendan McClancy, Walter Scott and Oliver Campbell - whose son graced the rugby fields of the world in more recent times - to name but a few.
In 1971 the new pavilion, situated at a new location on Station Road, was opened by Robert Ganly, President of the Leinster Branch of the IRFU.
They won the McAuley Cup (U15s) in 1976 and shortly afterwards merged their identity with Suttonians enabling the club to boast a very strong Juvenile Section.
The club finished thirteenth in their first season of AIL Division 2, having risen to the lofty heights of joint third at the Christmas break.
At the end of the 2016/17 season the Club avoided further humiliation by winning a Relegation Play-off against Carlow RFC and barely securing its place in the division.
The following season heralded a new successful year, culminating in victory in a Promotion Play-off game against DLSP to gain access to Division 1A again.
However the fortune of other Leinster clubs relegated from the AIL went against Suttonians, but the future looks better than it has been for many years with a strong coaching team and a united group of players.
The decade also saw the emergence and success of women's rugby at the Club, with the Ladies 1st XV engaged in the Leinster Division 2 and narrowly missing winning the league in 2018.
That same year however, the Ladies 1st XV won the Leinster Rugby Paul Flood Cup,[1] disposing of three Division 1 teams along the way to reach the final.
They won promotion to the AIL leagues with wins over established women's teams in a tough qualification process.
Records Founded in the 2002/03 season, the Suttonians Academy was generated with the aim of identifying and working with elite players among the under 18 and under 20 age grades who have the potential and commitment to develop to AIL Division 1 standard.
Specialist additional coaching in a variety of areas is provided to aid those players in their quest to improve the required skills.
With a strong, vibrant Minis section (age 6-12) Suttonians' fledglings take to the pitches on Sunday mornings and some midweek evenings.
A large number of Suttonians Minis have gone on to represent Leinster and Ireland at under-age level and often do not return to the nest, instead favouring the lure of AIL Division 1 rugby after leaving school.
Former Leinster, Melbourne Rebels and Western Force hooker Tom Sexton started playing rugby in Suttonians' Minis set-up.
The Minis 'exodus' impacts hardest at Youths level (age 13-18) as Suttonians has been in a position where restocking in terms of numbers and quality has left the club and coaches with a hard task.
