Boy name to honour LYDIA?

I have a Lydia in my life who is hugely important, and I always wanted to honour her in my baby’s middle name. If it’s a girl, mn will be Lydia (easy!) but if a boy, what names could work?

I wondered possibly Lydian, like the people of Lydia in ancient history, but fn also ends with -an so it doesn’t sound great together…

Any ideas?
