I thought Alpha Xi Delta had the most liberal policy. Can't really remember, but I know a lot of chapters are now including "steps"


Alpha Xi:
Definition. An Alpha Xi Delta legacy is the granddaughter, daughter, sister, or niece of an Alpha Xi Delta member in good standing. Where there are equivalent step- or half-relations resulting from blended or other non-traditional family structures, a young woman is considered a legacy if the Alpha Xi Delta member considers her to be one and asks that she be considered as a legacy on the Potential Member Profile.

Zeta:
Legacy: a potential member whose mother, sister, or grandmother is an alumnus or active member of that particular
national or international sorority
