Before anyone thinks of making comments, I should point out that my wife and mother are both called Ruth (and we are talking about two different women, before anyone starts speculating about family relationships in Worcester). The question of this thread arises from an episode of Friends which we've just got round to watching (I think it aired in the USA a couple of months ago). In it, 'Ruth' is treated as a name belonging only to a woman over 60. The same isn't true in the UK - it's never been a very common name, nor has it ever been very rare either. Age-related names in the UK would be names like 'Florence', 'Ethel' or (for men) 'Stanley' or 'Wilfred' (though these are now having a tiny resurgence). Was the loss of popularity due to Babe Ruth?
