Put off by popular boy names, or...? Help!

I had a baby boy name I've always loved and decided I would name my son since I was oh... 13? 
I guess it happens to be very popular this year. My MIL keeps saying we shouldn't name him that because everyone else will have that name... and she's starting to effect me by constantly saying that. 
Would you be put off by this? What're your thoughts? Would you go ahead and name your son that anyways, or feel a more unique name would be better? 
Daddy and I can't seem to agree on anything else, either... confused 🙃
