You my also find the name spelled Hogge, Hogh, Howg, Hoig, Hoige...well, you get the idea.They are all the same name which is, now, most commonly spelled Hogg, Hoge or Hogue.
You cannot always depend on spelling alone to determine the identy of an ancestor. Most of the time the spelling was determined by the agent who entered the name and not by the person being named. This is especially true in Scotland and America during the Colonial Period and still occurs with new immigrants today.
Incidentally, most people believe the name to be derived from the animal. This might be true if the Scots of the time spoke modern English!HOGA is actually an Old English word (you remember Beowulfe?) which means Careful or Prudent. This is more likely the origin of the earlyHogge, or Hoge name.
