Person in lodge adapted for seamen (9)

I believe the answer is:
freemason
'person in lodge' is the definition.
'Freemason' can be an answer for 'person' (Freemason is an example). I'm not sure about the 'in lodge' bit.
'adapted for seamen' is the wordplay.
'adapted' indicates an anagram.
'for'+'seamen'='forseamen'
'forseamen' anagrammed gives 'FREEMASON'.
Can you help me to learn more?
(Other definitions for freemason that I've seen before include "who's in order" , "Brother" , "who could be in order" , "Member of mutual help fraternity" , "One on the square" .)
