Can I say this ? using fronting -

" 'Twas of my own accord I came," said Robin.

"Ba é ar mo chonlán féin gur tháinig mé," arsa Robin.

"(Ba/Is) ar mo chonlán féin a tháinig mé," ...

Fronting uses direct relative clauses, i.e, a instead of gur.
No need for a pronoun é here.

Go raibh maith agat.

I'd write "Ar mo chonlán féin a tháinig mé." without a copula.

But I wonder what happens if I'd choose ba in the beginning.

Is it
B’ ar mo chonlán or Ba ar mo chonlán, i.e. b' or ba?

What would be the correct spelling?

(I find both, perhaps "b’ar" rather with lexicalized idioms such as "ar éigean" and "ba ar" with the real preposition ar.)

Ceadaíonn an Caighdeán Oifigiúil Athbhreithnithe 2012 an dá fhoirm a úsáid roimh réamhfhocal, roimh fhorainm réamhfhoclach nó roimh dhobhriathar. > "ba/b'aici; ba/b'ann; ba/b'as" etc. (Smaoineamh maith atá ann, ach níl "lexicalized idioms" luaite ann ar chor ar bith ).



(Edit: Just correcting what I mangled in previous editing.)

Here's another word that I don't know how to put into Irish, the verb - to ring. Here's the context:

Robin had plenty of gossips to spread the story of his wonderful adventure - Passage, Monkstown, Ringaskiddy, Seamount, Carrigaline - the whole barony of Kerricurrihy rung with it.
(Perhaps I could translate it as 'reverberated')
This is perhaps an off-topic question, but I understand that the mansion Ronayne's Court was demolished in 1969 and they put a petrol station and a sewage works in its place, but they did recuperate the chimney-piece with the carved inscription on it. It is said to be now in the foyer of Blackrock Castle, but I can't find an up to date picture of it. Is there anyone from Cork who could confirm this ? I can't find any pictures of Ronayne's Court either - which was said to be a remarkable building - before it was demolished. Do any exist ? There is a rubbing of the inscription on the Cork Archaeological Historical Society website. It is referred to in the story.

" - the whole barony of K rang with it."

- bhí sé le cluinstin ar fud/ó cheann ceann bharúntacht K
Or possibly (with dictionary help) - bhain sé macalla as gach carn de bharúntacht K

Go raibh maith agat. Yes I saw the word macalla in the dictionary too, but wasn't quite sure if it was the right one to use. Would you need to put in the definite article for - (an) bharúntacht Chiarraí Cuirche ? and would the meaning of Cuirche have anything to do with the crest of a bird or perhaps just simply - a crest ?

No, the def. article can't be used. When you have a definite noun "governing" (as the Christian Brothers put it) another definite noun in the genitive, the governing noun loses the article: fear an tí; teach mo dheartháir; Uachtarán Mheiriceá/na Fraince. etc., and obviously you know this since you wrote 'staighre an fhathaigh'. But you might not know this rule also applies to the likes of: 'the city of Galway/Galway City' - cathair na Gaillimhe; '(the) County (of) Derry' - Contae Dhoire; 'the barony of Kerricurrihy' - barúntacht Chiarraí Cuirche.

I have no idea about 'Cuirche'. FGB gives 'cuirce' as the genitive of 'cuirc' (crest/tuft).
