Safari search field auto-populates with an email address

Hi. Whenever I type 'ska' in the Safari search field, it auto-populates to the following phrase: "sold k**********x@gmail.com CA". I'm not typing the real email address, as it is someone's name and I'm assuming it's a real email address. I do not have this email address in my contacts on my phone, or anywhere else in any accounts that I have (that I know of). Would anyone know why this is happening, and how can I stop it from happening, other than just turning off the general auto-populate option? Thanks!
