The Durham and Northumbria Universities study, both based in the UK, suggests that a fear of prejudice made the Irish immigrants steer clear of giving their children Irish Catholic names, a trend also seen in today's society among other immigrant communities elsewhere in the world.
The study, which looked at over 30,000 records, found that the number of Irish Catholic names was dramatically lower among the second generation Irish in all seventeen counties studied, whilst the frequencies of English Protestant names went up.
