Fantastic work again Kris! I am going to look back into my notes because you now have me doubting Mary Ann Burt's death!! ( in 1844). She is certainly on the burial register for Woolpit then but I am sure I have something somewhere else about her.
The Burt family in Ipswich in later censuses I have come across before and had wondered if they were related, certainly Mary Ann and I think Fanny appear in the 1881 census, together with Robert the younger plus family, all living in Ipswich.
Sorry I can't help with the Allingtons, I must also see if I can find out anything about the Mannings.
Thanks yet again for your very generous help
Alison
