My name is Parker, the closest thing to a nickname I ever got based on my name was “park” or “parky” LOL My mother wanted us to have un-nickname-able names.
Walker was a top choice for our babe. We ended up deciding on a different name because Walker just didn’t FEEL like his name. We joked a lot that his nickname likely would have ended up being TR or Tex (because of Walker, Texas Ranger). Which I honestly kind of loved. Both of our girls ended up with nicknames that didn’t have to do with their actual names. So it didn’t seem too out there.
Could do Wallace nn Walker Or Walker nn Walt or Wally
