Ah, it seems that we think alike, brother. It just so happens that I have accumulated what occupational data that I could cull from the Description book. It is an interesting slice of the Irish society of the day; mostly farm laborers (sorry, labourers) but a few skilled workmen as well. A tin worker, tailors (taylors...), shoemakers, etc.
I'll try to get them posted along with some other info that I have as well.
All the best......Mark
