Ann Whorlton gave birth to an illegitimate son, George Whorlton, baptised in March 1818 at Hutton Rudby, Stokesley (N Yorks). In August 1819 Ann married Thomas Honeyman, a weaver, and went on to have several more children.
In the 1840 census George is with his mother & stepfather and is recorded as George Honeyman. Was Thomas the father all along - not sure - but George seems to have identity confusion for the rest of his life:
1841: Marries Hannah Simpson as WHORLTON
1841-1849 George & Hannah have at least three children - all christened as WHORLTON
1851 Census: Family recorded as HONEYMAN. George is a licenced hawker.
1851-1860: At least five more children born, all christened WHORLTON
1861 Census: Family recorded as HONEYMAN. George is now a Grocer & Draper.
1863-1865: Two more children born, both christened as WHORLTON
1871-1901 Census: Recorded as HONEYMAN. Occupation Grocer & Draper
1902: Death recorded as HONEYMAN
George's children seem equally confused, with some marrying under their birth name Whorlton and others marrying as Honeyman (I descend from Richard - born 1847 as Whorlton but married 1866 as Honeyman). The males that married as Whorlton also seem to switch to Honeyman on the census but, like their father, christen the children as Whorlton.
I don't have all the certs but those I do have confirm the BMD names as above, and for each child on the census as Honeyman I've found a matching birth as Whorlton.
Permanently ditching one surname in favour of another I can understand, but try as I might I cant come up with a decent theory as to why the family kept switching between the two names - and not just one generation, but at least two.

Any thoughts please?
