I love
Luca, though I think I prefer
Luka. I go back and forth on this, but
Luka tends to look like the more boyish spelling to me--and it's one of the few names I love the look of the K in.
In any case, it's certainly masculine enough for a boy and doesn't need a nickname. If you went with one, though, I'd go with Luc/Luk rather than
Luke; the E on the end makes it look like a whole other name (which, of course, it is) rather than a nickname. If I had a kid named
Luka, I'd probably call him
Lucky, myself--but I don't expect that to be a popular option around here.
Let's see...Luca/Luka middle names.

I have a hard time coming up with very Julia-ish names, ha. I tried to stick with the straight and narrow of traditional boy names, but it's simply not something I can do. ;)

"Yeah. It's Latin for 'kick me'."
