Fergus is depicted as a charming and attractive young man with striking looks and a charismatic personality, making him appealing to young women. However, he lacks essential qualities that would make him acceptable to more traditional and conservative families in Scotland.
Specifically, Fergus does not possess material wealth, a stable income, or a proper family name, all of which are significant factors for parents seeking a suitable match for their daughters. Additionally, he has lost a hand, further complicating his desirability in the eyes of a conservative society.
