Fortunately we have a family tree on the Cardus side that goes back to 1676, so I could.
The required names were from a couple of generations ago but I emailed across the ridiculously large pdf anyway.
My brother looked at it and found an unusual name: John Mountain Cardus.
I know nothing about John Mountain Cardus but that middle name brings with it expectations of great things. Or perhaps it smacks of unduly ambitious parental expectation.
Either way, Ian Michael Cardus fancies a name change to become Ian Mountain Cardus. I think it might just suit him.
