Idea help: one syllable name with a “k” in it?

Hello ladies,

I really like the name Luke for one of our boy twins, but can’t sell my husband on the name Luke because of someone he knew in high school. Any ideas for something similar to Luke? The other twin is going to have a two syllable name and my daughter has a 3 syllable name so, I have it stuck in my mind that it needs to be a 1 syllable. Like 3, 2, 1. I know that’s silly, but ¯\_(ツ)_/¯

Also, we know a Nick in the family, a Jake, Mike and Scott in the family and I know someone who named their son Blake who I really don’t like (the mom not the son) otherwise I would love that and a close friend who has a son named Jack. Why not Luke!? Oh well. I appreciate any suggestions. Thanks ahead of time.
