In the same season, it was a runner-up in the Wigtownshire Cup, albeit in part due to there only being three entrants; it is recorded as having won the 1929–30 tournament but that may have been by default.

At the end of that season two of the Garlieston players (Bertie Allen and Jock Kelly) rescued a third (William Murray) from drowning in Garlieston harbour after he got into difficulties while swimming.

[1] Garlieston also played in the Southern Counties League on an occasional basis in the 1920s and 1930s, including every season from 1933–34 until the League's final season in 1936–37, although without any success of note, finishing bottom three times.

The club gained a temporary boost in March 1937, when Whithorn, which had stopped playing the previous season, threw in its lot with Garlieston.

The name was revived in 1952 for a new club which only lasted a couple of seasons.
