As a GenX child of Boomers it is still weird to me that most of their kids are in fact Millennials. I'm the oldest child, my siblings are Millennials, and I still find it weird. idk why.
It's a little unusual, but not unheard of. My wife's Dad was just barely a Silent and her mom is just barely a Boomer. Wife (like me) is solid Gen X. Depends partially on how early the parents start the kid train. And of course these generational labels aren't all perfect. There are exceptions to everything. So your siblings may in fact not be idiots.
