What are some masculine nicknames for the name Harlan?

Also still undecided on the spelling so throw some suggestions on that my way too. Haha

We’ve had the name Harlynn picked out since our first pregnancy. That was a mc. Then we had two boys. For our last pregnancy (whenever it may be) I want to use this name regardless of gender. The feminine spelling includes my Mothers middle name “Lynn” so that’s why that spelling means so much to me but I do realize it’s very feminine.
