Gertrude, possibly Gertrude Baxter, was a human woman.
Description[]
Gertrude was a slightly older cousin of Martha Ravenswood's, who spent her life stuck in a menial job in the Thunder Mesa saloon, cleaning it up every night. Her dismal example discouraged a young Martha from seeking an honest job, much like how her older sister Mary's experience with marriage dissuaded Martha from seeking a husband (until, that is, she met dashing robe Henry Ravenswood).
Behind the scenes[]
Gertrude was mentioned in the unofficial 2020 story Enchantée. Her last name is not mentioned, although if she is the daughter of a paternal uncle of Mary's, it might well be the same as Martha's maiden name as posited by Enchantée, “Baxter”.
