Is it Eckley ot Heckley?

I want to my recent post about sylvia's character development, another reddit user started arguing with me calling me a doofus for spelling Eckley without the H. I tried to explain to him Hey not everyone spells their name the same way gave him Sarah and Sara as an example but he keeps arguing "Heckley is short for Hercules, watch the show." So now good people of reddit I ask how in fuck is it spelled?
