<human>: Can you condense the text into a few key points?

In a nutshell- my mother's family ("jones") has no surviving heirs that will produce children and her direct family line will die out. I would like to take her last name and hyphenate it with my future spouses ("king"). He will take this last name as well (we will both be the jones-kings).

Why I need help: I don't want to be a dick and make my dad upset. He is assuming I'll take my new spouses name anyway, but here I'm afraid what I'm keeping will be what hurts. *But* it is so important to me that my new name is reflective of the family I'm creating and includes both our names. I've been using my maternal last name hyphenated with my paternal last name since high school (jones-stephens). I'm not sure how to be delicate about this or if I should just forget the whole thing and hyphenate. In other words: help!
<bot>: should I be the jones-kings like I want or should I suck it up and be the bass-kings to make everyone happy and family reunions less awkward.
