Rugged pioneer, maybe a foreman in a cattledrive or a former one?
Dig it. Current or former is fine. Making a character, as you've seen, is pretty easy.
I can post more, but just having the PDF handy is probably all your need. Let me know if you have questions.
For the adventure, way I see, you've been summoned by someone for help. Who was it? Your brother? An old friend? Someone you knew from the war? And old flame? A mixture, because your brother wedded your old flame when you wouldn't settle down with her? That fancy woman from England who was trying to open a shop in a rough town you warned her about?
Start giving this some thought, but it might be easier after you develop your Background and Heartstrings.
