History:

Wars or political changes might have scattered people with this surname, as could people moving for work or other reasons. The name itself might have changed spelling over time, or even been adopted by unrelated families.

Description:

Adding an ia might give you Hessia, a common European suffix. Less likely, but possible, is Hessah (a double a). Or, you might see Hesser, a German-style suffix. But without knowing where this surname comes from, these are just guesses.
