How do you tell tempo for indications in English

[Patrick Horgan]

I'm setting some of O'Neill's Irish tunes, and the tempo indications are 
(a selection):

Animated, Boldly, Cheerful, Cheerfully, Gaily, Gracefully, Moderate,
Plaintive, Plaintively, Playful, Playfully, Rather slow, Slow,
Slow and distinctly, Slow and mournful, Slow and tenderly,
Slow and with feeling, Slow with expression, Slow and feeling,
Spirited, Tenderly, Very slow, With animation, With expression,
With feeling, With spirit

What do you do with that?  I can find tables of usual tempo ranges for 
italian tempo indications, but I have no idea what to do with these.  
I'd like them to be authentic, in that the midi file would be about as 
fast as the tune would usually be played in an Irish pub.  Does anyone 
have any ideas?
