Recently I've met an Éimí (Amy) and today I read about a Fíbí (Phoebe).
What is going on? 
This is no different to when Americans get all kreative with the spelling and call their kid Emmaleigh rather than Emily. And everyone agrees it's a bit naff.
If you like the name Phoebe just go with that, rather than trying to Irishify it in a comical way.
I'm not being a purist and asking for a return to the days of Gobnait and Dymphna (may God watch over all the poor Gobnaits and Dymphnas) but the advent of Éimí and Fíbí is a bit silly to me.
No offence to any Éimís and Fíbís if they're reading. I'm sure yiz are wonderful.
