History:

Bugatha: This surnames spread likely involved interesting movements of people and where they settled. Forced moves, maybe due to wars or political problems, could have scattered people with this surname. Or, people might have chosen to move for jobs or other reasons, creating Bugatha families in new places. These movements would have affected where this surname is found and might have led to slightly different spellings or pronunciations. Where people chose to live – near resources or family – also shaped how widespread this surname became.

Description:

However, we can guess at some possibilities. A shorter version might be "Bugata". Dropping the final "a" gives us "Bugath". Adding an extra "a" might result in "Bugaatha".
