Final answer:
Peyton Farquhar's wife and children are not mentioned as being present at the hanging in 'An Occurrence at Owl Creek Bridge'.
Step-by-step explanation:
In the short story 'An Occurrence at Owl Creek Bridge', there is no indication that Peyton Farquhar's wife and children attended the hanging. The text describes the military personnel and the execution setup, but it does not mention any family members being present. The author, Ambrose Bierce, focuses on Farquhar's thoughts and perceptions leading up to the hanging, and readers are left to infer that the hanging was a military affair without civilian witnesses.
