4 letter boys name

[Foxtrot101]

I have realised that by sheer coincidence myself, DH and DS1 all have 4 letter middle names.
We chose a name that we loved for DS1s middle and never thought anything of how many letters it had, but now that I've seen the pattern I can't unsee it and want to give DS2, due soon, a 4 letter middle name as well. I've been googling but so many suggestions are name shortenings rather than genuine 4 letter names (eg. Alex).
Please inspire me with all the 4 letter boys names that you can think of, that are not a derivative of a longer name.
Thanks!

Thanks everyone! So many suggestions and loads we hadn't thought of. Going to go through them all and make a list of ones we like. First name undecided at present so will have a long list for middle names to match with the first name shortlist!
