My SIL (DB's wife) loves the name StJohn, but doesn't like the spelling. I understand this, as people will often find it confusing and read it as Saint John. I would therefore steer clear of it.
However, she's decided (DB isn't interested in names, so she's choosing), that "Sinjun" is the best solution.
AIBU to think that this is silly? Their DS's last name (he's a couple of days' old) is Smith.
Neither SIL or DB are pretentious people, btw.
I appreciate that SIL or my sister might recognise who this is posting. but it is ok as she knows I think this is really daft. We get on well.
I thought that the replies on here would be useful to either tell me to mind my own, or persuade her to go for a different monker.
