<b>It makes people think about what’s “normal,â€ and if there’s really any such thing.</b>

Your statement about "normal" is dead-on for me. Between myself, my four parents and my five siblings (and three siblings-in-law), I have a family with six different last names. We may not be a "normal" family to some people, but so what? 

One of the reasons I usually do away with the "steps-" and other prefixes is because it gets so complicated and confusing with all the names. In my mind, a family is a family regardless of whatever last (or first) names are involved. A rose by any other name would still smell sweet and a family by any other name(s) would still be a family.
