I would desperately like to sit down and chat with my gg grandmother Mary who was born at Kingsbury Green circa 1801 and married my gg grandfather Henry Holmes circa 1820 (?) and settled at 10 Mount St Grosvenor Square where he had his hairdressing business. The very first question I would ask her would be, "Please, great great granny, WHAT WAS YOUR MAIDEN NAME?" The second one would be, "Were you his first wife, or did he marry you after she passed away?"
