This is about my Great Great Grandmother Martha
1851 Census
John Daw 1811 Thursford Norfolk
Wife Mary Daw 1814 Great Bircham Norfolk
Children
James Daw 1837 Bagthorpe Norfolk
George Daw 1839 Bagthorpe Norfolk
Sarah Daw 1841 Bagthorpe norfolk
Harriot Daw 1843 Bagthorpe Norfolk
Robert Daw 1846 Bagthorpe Norfolk
Thomas Daw 1846 Bagthorpe Norfolk
Martha Daw 1851 Bagthorpe Norfolk = My Great Great Grandmother
In 1861 Census they have all changed their name to Gant and the mother is missing
When Martha married in 1873 for the first time to John Playford in Docking Norfolk she used the name Daw
Why would they change their name to Gant, maybe the mother disgraced them or one of the children, has anyone got any ideas.
Any help appreciated THANKYOU
