A married couple were astonished to discover they were actually COUSINS.

Marcella and Tage Hill, both 42, were browsing their respective family trees on an ancestry website called Family Search to get ideas for a name for their then-unborn first child.

At first they thought their great great grandma just had the same name - but soon the penny dropped that they were actually related.

Marcella and Tage discovered they had the same great-great-grandma, making them distant - or third - cousins.
