Wanda is dated to me. And my name is
Tammy which I'm okay with. But I wouldn't bestow it on a child now.
Crystal I think would be the less odd or dated name to see on a child now. It is slightly dated but I think it could work. As seeing all three of these names as a sibling set. I would find it odd, and very dated.
I would use
Tamsin or
Tamara or maybe even
Tamia with the NN
