Dealing with criticism over name...

My partner and I have come up with a possible name for our son, Jayce Lincoln but when our family asks and we tell them we get so much negative feedback about it. We really like the name Jayce but my mom hates it and makes it very clear. How do you deal with criticism over a name you like? Do you change the name or ignore them? After all, this is going to be my sons name for his entire life. ?
