Please keep the ideas coming.
I would say you have the answer there - it is likely there was some tension between the two Mullen families and the marriage was not approved of; they eloped to Dublin to avoid mayhem in the Tallanstown church especially since the baby was on the way.
DNA may help in working out the relationship between the two Mullen families. My great grandmother came from Inishbofin island; turns out others descended from a family with the same surname are not related. I suspect that my 2xgreat grandfather came to the island with the coast guard and wasn't related to the families already there with the same name.
