Sue,

If you enjoy singing these songs then I recommend you keep at it. Tradtional singing in Gaelic be it Irish or Scottish is something that a minority of people are trying to keep alive day to day. I do alot of Irish singing and traditional singing. From word of mouth, I now have 12 children from 6-14 here whom I try to "teach"...by teaching I mean, give them songs with the Irish and English meaning, put in ornamentation and generally help them with finer details going into competitions.
Ornamentation is something that can be learned and put into any song Sue, its understanding the song and putting the story out to your audience that is the key!
I really hope you dont give up on this, enjoy it

Marie
