History:

Bejjanki: This surnames spread probably involved interesting migration and settlement patterns. Forced migrations, maybe due to wars or political problems in areas where this surname originated, scattered families. Think of big population shifts; some Bejjanki families settled in new places. People also moved voluntarily, seeking better jobs or lives. Maybe fertile land, new trade routes, or growing cities attracted Bejjanki families, leading to new settlements and wider distribution of this surname.

Description:

However, I can guess at possible changes. Maybe simpler spellings like "Bejanki" or "Bejanka" exist. Adding things like a family name (like "Bejjanki Reddy," if Reddy is common where this surname originated) could also create variations.
