I love both names.
Eleanor is one of my best friends names, and so I'm used to it. Plus, there are so many nn possible (
Elle,
Ellie,
Nora,
Lea?). As for
Evelyn, I think it is gorgeous, and I don't really see it as onenof those old lady names. And I would not use it as a sibset. I'm staunchly against same-letter siblings or families. It's tacky.
So love the names, and sorry about you husband. :)
