I found that the word Logan meant more than a name for a person with red hair. It can also refer to a rock in a state of equilibrium that is shaken by a slight touch.And it sounds very similar to logger.
This corresponds to Logan's red hair, bad temper, and work as a lumberjack.
It's an interesting Easter egg for me…I am non-native English speaker.Perhaps it had already been discovered?I'm still trying to find something similar in other people's names:P
