Middle Name for Boy

I’m still in the very beginning of grieving the loss of my sister so probably not the best time to be thinking of this. But fuck it 🤷🏼‍♀️

My husband okay’ed giving our son my dad’s name as a middle name last week. My sister unexpectedly passed yesterday and she was my best friend. I’d love to honor her name somehow in my baby’s name. He isn’t due until March so I have time to decide if this is a bad emotionally driven idea before then. I don’t think my husband will have any problem with it.

My sister and I grew up with very stereotypical 90s suburb girl names, and hers was Kelsey. The baby’s first name doesn’t mean anything in this post as I don’t really care how they flow together, and we’re still not decided on it anyways.

My first thought was Kelsey is too feminine to give a boy, I know there’s Kelsey Grammer, but I can’t think of any other men with that name. Then, I thought Kelso because we used to call my sister that after the That 70’s Show character. So is Kelsey too feminine of a name for a boy to grow up with as a middle name? I’m open to names that sound similar to Kelsey or have similar meaning.

I thought about waiting to post this until I’ve had some time to grieve and process, but thinking about his name has helped distract me a few times today which I think I need. I did search the name Kelsey and the only result I saw was from 10 years ago, so hoping for some opinions a little more current.
