help with middle names please!!!

Kady

DH and I were talking yesterday because I had a little break down because someone said happy mothers day to me. I had a miscarriage in December, so this mother says is harder than ever. but this lead us to talk about babe names, we have a few reptiles that we have named after Vikings or Norse mythology. we were obsessed with the show Vikings when we started getting the reptiles. we talked about continuing the little name tradition we now started, but then the names we landed on aren't exactly true viking names, but they sound like they sort of could be.

Titan for a boy

Lydia for a girl

we are completely stumped on middle names. DH wants to try and use something from my family for a boy, Lee has become a bit of a tradition for middle names. but I kind of want to move away from that one. I would love to use a variation of my dads name. William, I have a nephew already named liam so a different variation than that. or trying to use something from my cousin who passed a few years ago, Anton. or something that has nothing to do with a family name. I'm open to pretty much any suggestion.

for a girl I honestly don't know, just something that goes with Lydia.

please any suggestions would be so helpful!
