A legacy is a daughter, sister, grand-daughter, or step-daughter of an Alpha Gamma Delta who is an initiated member in Good Standing with the Fraternity.

My guess is that if it is step-sisters who grew up together, it would count, but if they grew up separately it wouldn't? It does seem kind of odd though!
