LochielCameron was created in those years that it was unduly fashionable to write about muscled Highlanders. Although Lochiel is an officer in the famous 42nd Highlander Regiment he is actually not born in the Highlands.
His men think he is a bit foolish to marry a clan chief's daughter, a decade his senior, while he has so much going for him.
Although Lochiel might have had some thoughts on the subject he still does not know that he is actually a son of Jonathan Montgomery, duke of Rothford.
I see Lochiel as a (young) man who doggedly tries to do his duty and to please quite a lot of people without really regarding himself. His 'honor comes first' ideal is greatly disturbed by Lizzie and then it turns out there is no way back.
What you will see in Novel 1 - 'A Lieutenant at Large' is that things just seem to happen to Lochiel. He is mostly a victim of circumstances.
