name dilemma!

I have a name dilemma that has left me a bit sad: my husband and I decided long ago...before we even started trying over two years ago...that we were going to name a boy after my grandmother who will be 100 in August (Oliver, her name is Olive) and his grandfather (James). Yesterday one of my colleagues had a baby and he and his wife named their son Oliver! I wouldn't generally care, but I'm not the biggest fan...We considered swapping the names, but then his name would be the same as a very famous person, which I don't love. Ultimately, I don't think we will change, but I just needed to vent a bit because we aren't sharing the name with friends and family and I'm feeling a bit sad about the whole thing....very The Office scenario...
