One unfortunate aspect of choosing names was caused by religion. I don't know if this happens in the US, but in Scotland and N.Ireland, religious differences entered every part of life. As Presbyterians, it would have been most inappropriate to give the children an 'Irish sounding' name. Names like Patrick or Siobhan were almost exclusively Catholic. We stuck mainly to names like William, Andrew, Margaret, Ann etc.. Traditional Scottish names were more acceptable.
I expect things are changing, but now it's all 'Celebrities' with poor kids called 'Chardonay' or a diminutive name like 'Freddie'.
I once heard that the most commonly asked question in the Citicens' Advice Bureau, was "How do I change my name?" .
