On The Irish Traditional Music Tune Index site the alternative titles for Stack of Rye are listed as:

"Stack of Rye, The / Stack of Rye / Junior Crehan's / Stack of Oats / The Clare Hornpipe / Gerry Egan's (also as fling, also in E) (1st in set The Four Stacks (Rye / Oats / Wheat / Barley) on KCrhn; 1st in set Two Flings by Junior Crehan on Hmmrs) (composed by Martin "Junior" Crehan)"

There is some useful information on that page. I haven't seen that site before. I'll bookmark it for personal future reference.
