I am 65 and have an unusual French name which nobody had when I was in school in the 50's and 60's . I have always shortened it because nobody pronounces it right and that annoys me, it is heard a bit more often now but still not common. My. Granddaughters have names that are lovely but everyone calls them by a shortened version and although living in England our side of the family is Welsh so they have Welsh second names which are very traditional in Wales.
My daughters friend called her second child Reggie, my FILs name was Reginald. My MILs name was Lynda but I have a friend a bit younger than me who is also a Lynda with the Y spelling. I have friends called Patricia, Christine, Susan, Lynda, Kim, Cheryl, Alison, Nikki(Nicola), Catherine, Margaret, Gloria, Lyndsey, Ann, Gillian,. Not many of them are used by today's mums .
