Just like how Betty Crocker is a DZ (amongst other affiliations) and how Carly Simon and Madonna are AGDs.

Back to the original subject -- everyone knows that one of the Alpha Gam Founders helped design the TKE Coat-of-Arms, but that doesn't necessarily make the TKEs our brother fraternity. In fact, Emily Helen Butterfield has a historical connection with SEVERAL fraternities and sororities because she helped design their Coat of Arms as well...she was an expert on Heraldry.

Even though the Alpha Gam official website doesn't list her contributions to Greek Life by detail, I know that several other HQ sites do, TKE being one of them, as you can see from the link above.

So yes, historical connections are wonderful, but that =/= brother fraternities/sister sororities.
