do thaisbeáin sé, ’n-a ghníomharthaibh agus ’n-a bhéasaibh agus ins gach aon tsaghas deighleála idir é féin agus daoine eile, go raibh beann thar bár aige ar an gceart, ná déanfadh sé éagcóir ar aon Chríostaidhe, pé ’cu caraid nó namhaid é, pé ’cu íseal nó uasal é.

where it says: ar aon Chríostaí, pé acu caraid nó namhaid é - I was surprised to see "caraid" and not "cara", as "caraid" is dative only - unless Connemaran usage of caraid as the nominative is being seen here?

Críostaí is dative in this sentence. Is it possible that the dative is being carried forward onto caraid too?

Pé acu - as far as I understood was followed by a relative clause. [eg. pé acu a ghlacfad nó ná glacfad] So in pé acu caraid there must be a deleted relative copula: pé acu [is] caraid nó namhaid é - which makes the dative totally incongruous?

Ó Dónaill gives caraid as a variant nominative form. What has Conamara got to do with West Muskerry?

No.

Yes, that is how I would understand it, that there is a hidden copula there.

Connemara has nothing to do with Muskerry of course - what I meant was the PUL might have been influenced by the Irish he read. OK, it seems just a random dative for a nominative.
