So James Gilbert Ireland and James Gilbert Ireland look like duplicates to me: same birthdate, birth place, death date, and death place. The only difference I see is different wives, which, sadly, was fairly common, as women would die in childbirth and their husbands would remarry. (I've worked on profiles where the husband went through several wives. You'd think they'd learn to take care of them, but apparently not. )
On the other hand, both profiles were created by the same person, so it's possible that two cousins were born in the same town on the same day, led entirely separate lives, and happened to die in the same town on the same day, too. I don't consider that a likely scenario, but I don't want to apply the merge without checking, and right now, I'm trying to solve an entirely different Ireland mystery. So I'm noting the oddity here in case somebody else has the time and access to sources to follow up.
