Family Name Pressure!

My husband and I find out the gender of our baby tomorrow. I'm pretty sure it's a boy. A little back story-John is on both sides of our family. Husband is John Casey, his dad is Johnny, his grandfather is John Edward. My brother is John Zachary, father is John Anthony, and grandfather also John Edward. My family hasn't pressured me in the slightest, but today my husbands grandmother was pressuring me about if it's a boy naming it John. Every suggestion I have like Sterling she said "John Sterling" etc. I've considered using John as a first name but I'm honestly tired of it. My brother hates it and goes by Zach and even my husband goes by Casey. Am I obligated to name my son John? I've considered Zane because it means John but isn't John. If my family of Johns doesn't give a shit, should I bow down to make his family happy? I'm anti drama but not scared to put my foot down. Suggestions?
