Please suggest possible reasons why a family is using a different (false?) surname on the census while living away from their home base.
My ancestor Henry SPUR(R) married Caroline HINKS (poss. Hincks) in Nuneaton, Warks in 1846.
The 1851 census shows them living in Manchester, Henry is a stone mason, they have one small son William Henry - but their surname is SHEPPARD. However, they have baptised their son as SPURR.
The 1861 census shows Caroline a widow, with sons William Henry, Christopher, and baby daughter Elizabeth. Caroline gives her surname as SHEPHERD. (She couldn't write, so must have spoken her name, and the spelling is variable). But Christopher and Elizabeth have also been baptised as SPURR.
Caroline, a widow, returns to her home area (presumably Warks/Leics borders) and remarries in 1864 as SPURR. (She becomes Oswin).
Why is this family using a different (false) name for census purposes? Is Henry Spurr hiding from something? (criminal proceedings?)
Caroline re-states the different surname (Shepherd) in Manchester just after Henry's death in early 1861, but reverts to her married name Spurr when re-marrying. Was it 'safe' to state the Spurr, now Henry had gone?
I can't crack this, and I can't find the correct Henry Spur/r or Caroline Hinks (Hincks) on the 1841 census nor any suitable birth for either of them.
Extra details, potential clues:
in 1846 Henry Spur(r) gave his father's name as Robert Spur, carpenter.
In 1846 Caroline Hinks (Hincks) gave her father's name as William Hinks, carpenter.
In 1851 "Henry Sheppard's" birth place is given as Sheffield.
Caroline's birthplace is given as Leicester, then Coventry, then Leicester.
Caroline's second marriage is in Coventry.
In 1864 Caroline Spurr gave her father's name as William Hinks, joiner.
In 1879 Elizabeth Spurr, daughter of Henry + Caroline, gave her father's name as WILLIAM Henry Spurr, stonemason. But both of her older brothers stated 'Henry Spurr' on their wedding details. Was he a William?
Caroline and her new husband set up home in Aston, Birmingham, and remain there. Why did they go there, in particular?
Where does the SHEPPARD/SHEPHERD come from, and for what reason or purpose were they using it?
Very grateful for all suggestions. I could be mistaken in any of the above details and if I am, please tell me. Thank you.
