Margaret O'Dell is one of the Fox's many neighbors. She has a 9 month old daughter named Katherine, who she overprotects, thus leading Paige to believe she is seriously nuts. Margaret O'Dell belongs to the same book club Andy is in, and that's how Paige started babysitting Katy (with a "k" Mrs. O'Dell says)
It is not known whether Margaret O'Dell is married. One time Paige gave a bunch of kid video games to them, which were really Peter's M rated games in kid cases.
