"Sigma Iota Chi"?

[exlurker]

There was (maybe still is ?? ) a small national sorority "Sigma Iota CHi." Founded in Louisiana in 1903, it was mainly in private junior colleges for women -- schools not recognized by NPC or by the Ass'n of Education Sororities. It was never particularly large. Some of the schools where it was located banned sororities, or eventually became 4 year schools, or went out of existence.

I know SIX existed into at least the early 1960s, and possibly longer than that.

Every so often an SIX badge shows up on eBay, just as pins from NPC, NPHC and NIC groups do.

I don't know whether SIX ever had a chapter at Widener or at one of the schools that joined together to form what is now Widener.

Some of the older editions of Baird's Manual have short mentions of SIX.

All this isn't a lot of help, but it is a lead to a possibility that your aunt's sorority was part of that national sorority, or possibly a "local' that had been part of national SIX at one time -- just guessing, could be wrong.

Good luck.
