My Dads sister and one of Mums sisters have bothed named their babies Lachlan. One is Lachlan and one is Lochlan, though.

I think if you're only gonig to be seeing her for family gatherings it will be ok, you don't seem to have alot to do with each other otherwise so it shouldn't cause to much confusion. Plus you get to call your little man Jamie, which I think it cute ><;;

If DF and I had a girl we were going to call her Dylan, and a good friend of ours has a son called Dylan - I ran it buy her first, though... and we had actually gotten the name of Desperate House Wives haha. But, blue bundle for us anyway!

Don't stress chick, there are worse things, even though it is annoying!
