1861 census RG 9/2092/136/page 1 Worcester Workhouse
Robert Featherstone age 13 a pauper born Worcester City

In theory Robert should be found in the 1851 census as he would have been 3 years old.
A search using Ancestry does not find a Robert of that age born in Worcester.

Does this mean he was recorded with the incorrect name or the age was wrong.
