I too would be interested in any information on hairdressers (but a bit earlier) as my 2g gfather was, according to family story, a hairdresser who travelled widely thoughout Europe hairdressing for the European monarchy. He was Wm Major probably b c1840 & m8/3/1863 when his occupation was a hairdresser. His daughter b1/4/1868 was brought up by her aunt so we assume that her mother died in childbirth (no record though) & he couldnt look after her because of his travelling.
Any info welcome
Tony
