Hog Shed or Hog's Head?

One of my ancestral surnames I am researching is Hogshead. Mary “Polly” Hogshead (1800-aft 1857}, a Cherokee Native American, was married to Jacob “Jake” Trammell. She drowned in the Little Tennessee River, in Franklin, Macon County, NC., while tending her fish traps. Her parents were Walter Hogshead, Jr. and Rebecca Ashworth. I have wondered if you pronounce the surname as “Hog’s Head” or “Hog Shed”? This morning on THE TODAY SHOW Sally Hogshead (pronounced “Hog’s Head” gave a review, sort of, of yesterday’s commercials on the Super Bowl. Mystery solved!
