|Portrayed by||Tricia O'Kelley|
is a rich mother from Richie's private school who often puts Christine down for being divorced, having a low income and being a working mother. Christine often calls Marly and Lindsay the "meanie moms". Marly has a daughter, Ashley. She is said to have had much plastic surgery, and can evidently no longer blink. In the fourth season, Marly became pregnant again and her friend Lindsay became so too, so they could do it together.
