Legacy officially special *after* initiation?
 

Phi Gamma Delta has "Fiji Sires and Sons" (http://www.phigam.org/page.aspx?pid=945) as an official order within the Fraternity of Fathers and Sons who are both members of Phi Gamma Delta. This is the only example I've seen being a certain type Legacy means something official within a fraternity/sorority *after* initiation into the GLO. Does anyone know of any other groups that have similarly special Mother/Daughter or Father/Son organizations like this?

I have a post ready to debut on the Sires and Sons anniversary. I think it was a wonderful photo opportunity after John Coolidge became a member of the chapter at Amherst, his father's chapter. And his father was living in the White House serving as President. There are still a few certificates signed by John Coolidge (his father had signed the original certificates). Unfortunately, John Coolidge had no sons, only two daughters. He was a humble and gracious man and in reading about him and hearing stories, I think he had the best qualities of his mother and father.

I have never heard of this type of distinction in any groups. Kind of cool.
