History:

Those who chose to move might have been looking for better jobs, farmland, or a safer, more comfortable life. Forced movements, while harder to track for this surname, might also have played a part; wars or political changes could have scattered families. Tracing the exact paths this surname took needs serious historical digging – looking at old records, property deeds, and census data would help.

Description:

However, I can guess at some variations based on how names often change over time. We might see this surname as Tantris (a shorter version, maybe), Tantray (a slightly different spelling), or even Tantrye (adding an e for style).
