History:

Bhunya: This surnames spread probably shows how people moved and settled. Wars or political messes might have forced some to move, scattering those with this surname. Others may have chosen to move for jobs or a better life. Where people settled depended on things like available land and existing communities. Over time, the spelling of this surname might have changed a bit.

Description:

However, I can guess at some possibilities based on how surnames usually change. We might see simpler spellings like "Bhuye," or slightly different spellings like "Bunyee." Less likely, but possible, are variations added to the name, like "Bhunye-Patil," if Patil was a common family name.
