This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
傆 combines the person radical 亻 with 原, but the exact historical development and original meaning are uncertain.
A person 亻 beside 原 (origin/plain) might suggest someone connected to origins or plains, but the meaning is unclear.
For ゲン, imagine a person 亻 standing on a plain 原 saying 'gen' as a greeting: gen -> ゲン.
