Etiquette dilemma..
We've received a Christmas card introducing their new grandchild Pheobe. I now have to write a card back congratulating them on said new arrival. At first glance I assumed they'd written Phoebe wrongly, then I googled and it is apparently a variant of Phoebe, though I've never come across it before. Do i go with their spelling as written in the card and risk offending them if they think I've misspelt it, or do I write Phoebe and risk offence for getting it wrong?!
Does anyone know of a Pheobe?
