The club continued for another 13 years without any success, until 1900 when a parish team under the name St Patricks captured the county title from Kilmihil by a winning margin of six points.

The Shannon Gaels club won the Junior A championship in 1941 defeating Clohanes in a game played at Kilmurry McMahon.

The following year, Shannon Gaels completed in the intermediate division and reached the final before being defeated by Kilmihil.

The fifties brought success which was based on a good youth policy under the stewardship of Vincent McGarry.

On 16 August 1970, Arthur Ford lifted the Jack Daly Cup in the Square in Miltown Malbay after a hard-fought victory over Kilrush Shamrocks.

This should have been the beginning of something of a famine for the other teams in the county but the following years did not bring the success the tremendous talent which existed in the parish deserved.

The Cusack Cup was won in '75 and '76 but this was scant consolation for what should have been numerous additions to the Roll of Honour list for the Senior title.

A victory in the round-robin stage (over Wolfe Tones) was followed by defeats to Éire Óg and Miltown Malbay and this saw the Gaels competing in the Senior B championship.

Defeats by Liscannor (after a replay), St Breckan's and, finally, Corofin resulted in relegation back to Intermediate level.

[citation needed] The Gaels' 2007 season saw relegation from Cusack Cup and also a failure to reach the quarter-finals after a defeat to Doonbeg in the last round robin match.

In the first round of the senior championship, Shannon Gaels overcame a seven-point deficit with ten minutes to go win by a point against Kilmihil on a scoreline of 2–10 to 2–9.

Shannon Gaels met St Joseph's Miltown Malbay in the final in Kilmihil on 26 July and led by 0–4 to 0–3 at half time.

In the final round robin game against Éire Óg, the Gaels ran up a strong seven-point lead early in the second half only to lose by three points.
