*techchick68: Boy, that’s an interesting topic. Although I don’t know the answer it brings up a thought with me.
I have Step Family…tons of Step Family! I often wonder what to call them. I get sick of saying “My step-brother’s aunt” my “step-aunt” and such.
To make matters even worse I call my step-brother “brother” only when I have to clarify the step-uncle thing…but step-uncle seems so obtuse.*
Here’s an equally confusing situation: My parents had three kids together. From their first marriages, my father had 2 kids and my mom one; these are my half-siblings.
To top it off, my dad’s ex- and my mom’s ex- got married and had a daughter; not really related to me, but I call her my quarter-sister. She and I have the same half-siblings, but for opposite reasons.
Since this all happened in the 50’s, the fathers did the “honorable” thing and surrendered their parental rights so that the other could adopt their children. So my mom’s first daughter is my half-sister & adopted sister.
We don’t usually use any prefix when referring to each other (although my half-brother calls his dad’s third wife his evil step-mother :)).
Since all six of my siblings (fractional or otherwise) are from 6-16 years older, they’ve all got a head start on the procreation. Add in the 7 niblings ( :)) from my wife’s siblings, and I have 24 niblings. Hence why I needed a collective term!
(I’ve gotta get “nibling” into print so that it’ll become an official word. :))
