quote:Bhí finne agus solasmhaire agus gileacht na hiníne ann, agus bhí folt óir na hiníne air; an t-ualach órga ar a cheann agus anuas ar a ghuallibh agus ar a shlinneánaibh.
I presume this passage is referring to the son of the daughter in question. "ualach" is literally a "burden" or "heavy load" and refers to the thickness and weight of the hair on his head.
Another word for "ualach" is "eire" and can be used in similar situations: bhí sé d'eire orm é a dhéanamh.
