DS due in a few weeks; dh and I have the same favourite name which is also a family name on his side with a lot of sentimental reasons for him to want to use it.
We've always wanted this name for a son and have been trying for around six years now.
Problem is, my sister called her son a very similar (shortened version of the) name about four years ago. (Think John/ Jonathan or Will / William).
I had told her before she had her son or named him that this was our chosen name if we ever had a son. I've no idea why she chose the name, as it was never a name she'd mentioned, but of course she can use any name she chooses and I certainly had no right or intention of "reserving" the name.
(if its relevant, she also used our favourite name for a dd for her dd too, but was quite open that she'd loved it when she heard me mention it and chose it as a result. Which is fine, it suits her dd perfectly and we chose a very different name for our dd - which we didn't mention to a soul until she arrived - lesson learned, better late than never!)
So now we have a dilemma - can we call our ds William when hers is Will? We can't, can we? We live quite a distance apart so they'd only see each other a fee times a year, but even so....
