Dad has another helpful name change by 1891

35 Heaton Park Rd South, Byker
Joseph Smith Head Mar 57 Baker Newcastle upon Tyne
Annie do Wife Mar 57 Norwich
Edith do Daur 18 South Shields
Meggie do Daur 13 Newcastle upon Tyne
RG12/4214/29/6
Could the move from Norwich and the name change(s) be linked - getting away/hiding from someone?
Interesting that they used their correct names for the birth registrations (and, if we have the right Edith, on her 1892 marriage).
