Hi angi
Just had a quick look on Free BMD, and found a Nellie Lott, b; june 1885. 2a 818 in Blean which I believe to be Kent. If she was born in June 85, on the 1891 census her age would have been 5 as they were done in april, she wouldn't have been 6 for another 2months. Was she born here and then moved to notts?
Good Luck
Julie
