Well, my name is Shilo and my siblings are Christopher and Amanda.
My boyfriends family always made my eyebrow go up. Kyle, Kendall, Kip, Kevin, Vanessa, and Leithi. Mom named all the boys K names and dad picked the girls. My siblings and I don't match at all but we're all step an half siblings and there's a 20 year gap from oldest (me) to youngest (my half brother) so that explains it.
A family at our church has four kids, the first three are:
Austin, Kyle and Eliana...they named their youngest Joaquin. I do not think this matches with the other three at all...(Sweet kids, and great family though!)
Also, a family I babysit for has 5 kids, Luke, the twins Cole and Joel, Dominico, and Glen.
And my cousins are Timothy, Jeffrey, Andrew, and Margarita.... (Yes like the drink...)
So it's Timothy, Jeff, Andy, and Margie/Rita....
I don't think sibsets have to match, it's up to the parents I guess. That being said, mine is mismatched. We have Brandi, Sandi, Sarah (me), William, Arthur, Samuel, and Anna. Though only my brother and I are full siblings. You had the at the time trendy Brandi and Sandi. Timeless/Classic Sarah, William, Samuel, and Anna and the quirky hipster (especially in the 90's) Arthur. I also know a family who has 4 daughters named Sia, Blossom, Eve, and Mykkynlii.
