If you can adopt someone just cause they're from a country that's in a Union with England surely Nadal is a better option? Quick though while Spain are still in the EU. Henman's Hill or Murray's Mound (I always think of his Mum when they call it that - urghh feel queasy now) would have to change to something beginning with N or R but that shouldn't be an issue. Rafa's Ridge..or maybe just call it the grassy bank full of cat owning utter twats.
That sort of thing.
Rusedski's Ridge has already been used so you will have to come up with something different.
