I don't know if my mother's ancestors belonged to any social organizations. I remember my mother being involved with school activities as I grew up, but I don't think she belonged to any formal organizations. My father's family was involved in groups associated with their church. The newspaper clipping below lists my great-grandmother Anna Niehaus Creeden as an officer for the ladies auxiliary of the Knights of St. John in 1936. This group was affiliated with the Immaculate Conception Church in Celina, OH. Several of my father's female ancestors were members.
Late update: I found out that my mother was a member of Alpha Iota Sorority while she was at Goldey College!
