I made it known what our chosen names were, for a long time before I fell pg. SIL fell pg first, and they decided that they would use my chosen girl's name as their chosen middle name. I was really upset at the time. I was pg by that point and although the name has boomed in popularity, I couldn't imagine calling my child anything else. In our instance, and child that my brother and SIL have are the only cousins my kids will have, so it was pretty important not to have the same names as far as I was concerned. I didn't have to do anything though - mum ended up mentioning it to my brother and they changed it.
I think it all depends on circumstances surrounding the situation. If you never see the people who have used the name you like, then I don't think it really matters. But if you see a lot of them, it could get confusing and one of the kids will no doubt gain a nickname. I've known quite a few European families where they've had a tradition of naming their first born after a grandfather - which means that many people in the same family have the same name. They all get around it by calling the people "Big John" and "Little John". I'm not a fan, but it worked for them. It seems to be mainly boys/men it happens to - and they all have the same surname too! Wouldn't want to get the mail mixed up :lol:
This time around, I've only told a couple of people our picked names. And given that we've changed our boy name in the last few days, well nobody knows that. I'm not too fussed though.
