I thought I had seen every permutation of the name Makenzie, but recently I saw McKinsy, I also saw Chaynne for Shane, Rile for Riley, Sidnye for Sidney, and Jacen for Jason.
Edited because II forgot Acea for Asa, and Carea for Cara (I think they were thinking Care-a, but her name was often mispronounced as cah-ray-ah)
I also saw the invented name Kenzleigh.
That's just in the past couple months - when I see odd spellings or invented names, I text them to my daughter and she to me. ; )
