I think I have made a big error.
All Warwick reg.
Elizabeth Ann Mansill born M1850.mmn Kelly, Eliza Ann Mansill died Sept 1852 aged 1.9m
Elizabeth Mansell born M1850. mmn Robinson.
Elizabeth Mansell died Dec 1852 aged 5.
The top one is the same person, the bottom 2 may not be the same person as the age doesn't match.
Elizabeth may be with them in Wales in 1861. Maybe William James is her son. looked after by her mum.
