I've been looking at the JIFSS Index at Bruce Olson's site
If you have access to old copies of the Journal of the Irish Folk Song Society you might look up:
Tiocfaidh An Samhradh; JIFSS #7, 19 (tune only)
Tiocfaidh An Samhradh; JIFSS #10, 11
Tiocfaidh An Samhradh; JIFSS #16, 27
Tiocfaidh An Samhradh; JIFSS #16, 28 (words only)

To help you calculate the date of the issue you are looking for, Olsen writes that: "Journal of the Irish Folk Song Society. Issues #1-1904; #2 & 3-1905; After #3 about one issue per year"
