Middle names

I'm struggling to decide if I want baby boy to have 2 middle names or just stick with 1.

I've had Hudson Kelso Millar in my head since I found out I'm having a boy, but lately I've been thinking of naming him Hudson Kelso Thomas Millar. Does that sound like too much?

Hudson is almost like a tribute to an uncle I had in New York, Kelso is my dad's middle name, and Thomas was my grandpa's name but also happens to be the father's name (who's not involved).
