The 1921 census did not require a statement of nationality unless NOT born in the UK. I am white and suspect I have a black ancestor, possibly as far back as 1800. No records state race. A family member has completed the 1921 census in blue ink. A note in black ink and a different hand, has been added in the column meant to be blank unless needed to state other nationality. This says ‘British born’. Other corrections (crossing out of children’s marital status) have been made in the same black ink and hand. Does this hint that their appearance suggested they were a non-UK national,
possibly mixed race? Were they asked ‘where are you REALLY from?’ on the doorstep or am I reading too much in to this?
