Who is the oldest housewife on the real housewives series?

As of my last update, the title of the oldest housewife on the Real Housewives series is held by Marysol Patton from "The Real Housewives of Miami." Born on January 9, 1967, she is older than many of her co-stars across various franchises. However, ages can change with new seasons and cast changes, so it's always good to check the latest information for any updates.
