From what I know Sigma lambda Beta and Sigma Lambda Gamma, fraternity and sorority respectively, call themselves cousins to Sigmas and Zetas because one of Sigma Lambda Beta's founders was a Sigma first and the Gammas are there constitutionally nound sister organization. They are like the Latino Sigma's and Zeta's. I have seen on collegeclub.com where they are included in the definition of "The Blue and White Family", along with the doves and knights....
