Jude, Emma & Eli are lovely.
I don’t think that Leo is too close to Eli. It fits in really well w/your crew. I like David a lot too. It seems like a good fit, & it’s a nice, kind yet strong, solid classic. Wilder is cute, but maybe a little…dare I say trendy? I don’t know. I think maybe it’s just Nameberry trendy! It doesn’t not fit w/Jude, Emma & Eli. It’s kind of a cool name.
For a girl, Isla is really pretty but is sort of tongue-twisty with Eli. Laura is pretty & kind of unexpected. It’s great w/your kids’ names. I’m not sure whether or not you’d get the pronunciation you’re looking for. I think it’s typically said ‘Law-ruh’?
Forgive me for any repeats, but how about…
Hope this helps.
