Sibling GLOs - Who's who's sister or brother organization?

[Shelacious]

Zeta Phi Beta must acknowledge the encouragement and support provided its members by the men of Phi Beta Sigma Fraternity, Inc., especially "Lord" Charles Robert Taylor and A. Langston Taylor. From the Sorority's inception, the members of Zeta Phi Beta and Phi Beta Sigma have successfully collaborated on a variety of community service projects, shared national, regional, state and local activities and developed and enjoyed the bonds afforded a sisterhood and brotherhood with a shared purpose. No other two organizations can boast of such a rich, mutually beneficial relationship that has resulted in a complete and comprehensive record of service to the men, women and children within our communities.

Zeta was not founded by members of Phi Beta Sigma to be the little sister arm of Phi Beta Sigma, but founded by five women with assistance from two members of Phi Beta Sigma Fraternity, to be a sister (female complement) organization with a shared purpose to Phi Beta Sigma. Oddly enough, none of our Five Pearls (Founders) married any member of Phi Beta Sigma.

The relationship between our two organizations is ratified in our respective Constitutions, and we do indeed share similar purpose and symbolism. On both the National and local levels, we try and conduct as many joint activities as possible, but the two groups are fully autonomous and operate independently of each other.

Just explaining the genesis and rationale for our brother/sister association because sometimes I hear some "out there" explanations!
