To start this off, the mother's maiden name on the children's birth certificates varies quite extremely, but Johanna appears to have gone mostly by 'Donovan':

Her year of birth seems to have been c.1811-1815. I did a search for you on irishgenealogy.ie, the site that holds the parish records for Kerry, but nothing obvious turned up. Unfortunately, from my experience of Kerry parish registers, it is often the case that there is no baptism record to be found when researching this far back; it is very much dependent on the parish. I have ancestors who were born in the 1830s in Kerry whose baptism records I cannot find.
Of these DNA matches you have, do they share any common ancestors? A particular Donoghue couple that they have in common?
Maybe someone else will have some other ideas.
