Isn't/ wasn't Ant one of the hosts of Britain's Got Talent?
Eug for
Eugene- I'd write Euge, since it shows that it's the soft g sound. This is my mom's cousin's nn. It sounds like huge, but with a y sound instead of the h.
I wouldn't call
Drea from
Andrea, Kel from
Kelly or Vick from
Victoria unusual, either.
Dalt from Daltyn- I know a boy with this spelling, and Dalt could work for any spelling of the full name. But he's always Daltyn.
When I sit and think about it, the only ones that aren't obvious are
Gaz/ Gazza, Jezz, and Muzza.
