Are you a Womble?
Yes, call it Great Uncle Bulgaria.
If you wouldn't call your child England, don't call it Ireland. It's an actual country to whose name it's in really poor taste to help yourself because you think it's a 'quirky', celeb-like child name. It also suggests you know fuck all about Ireland, and choosing a name because you saw it on a FB page about a child with cancer is really vacuous.
