History:

Pantam: This surnames spread likely resulted from people moving – either by choice, for jobs or better land, or because of things like wars. Where they settled depended on things like available resources and existing communities. The name itself might have changed spelling slightly over time, reflecting different ways people spoke in various places. Tracing the exact path is tough without detailed historical records.

However, similar-sounding names might be related. Pantom is one possibility – a slight sound change. Pantum is another, maybe from a different dialect or a writing mistake. Pantan is a third option, though a bit more of a guess.
