DNA-profiling website Ancestry is rolling out a huge update to its ethnicity database - and changing the ethnic origin of many of its customers.

The company says the database changes, due to be rolled out next month but showing up for some users now, make the results more accurate.

But for some users, they challenge what they had been told about their identity.
