History:

Illapu: This surnames spread likely involved people moving, both because they were forced to and because they chose to. Forced moves, maybe from wars or being pushed off their land, scattered families with this surname to new places. People with this surname also moved voluntarily, perhaps seeking better jobs or joining others with this surname already living somewhere. These movements shaped where this surname is common today. Pinpointing exactly when and how this happened needs more historical records than I currently have access to.
