Could be fun - like Nigels descriptions above, my great grandfather had a much younger wife, as he got older when he had Alzheimers setting in he took the family off to southern Spain. While there great gran had three children with dark skin and curly hair so I'm 7/8 English and 1/8 Spanish Moor. Funnily enough I can never find a tick box for that so I might ask for a narrative description.
Sexuality - I'm sure a good number of posters on here could put "Please refer to age box"
Religion - allotment holder
