?'s dates of founding or closing
 

Let me preface this in that this is research I have done on my own via old Quarterlies, internet, etc so it could include errors but I don't think so and I would welcome any corrections to the following:

Sigma Rho Bentley founded 1982
Beta Gamma Colorado 1924-1982/1990
Kappa Stanford 1899-1944/1978-1993/2011
Zeta Iota Virginia 1978-2000/2000 (revitalization)
Eta Boston 1883-1970/1984
Delta Cornell 1889-1998/1998 (revitalization)

This will help you get rid of some of your question marks, I hope.

Thank you so much Forgetmenotivy! I updated the list.

We still need recruitment dates for:
Southern Utah, Kettering, Lafayette (9/4-?), Montana (9/4-?), Linfield (9/10-?), Bentley, SIU-Edwardsville, Wilfrid Laurier (Canada), Adrian and Hofstra (holds Informal Recruitment only)

The only dates I need for current chapters are:
Washington State - 1945-?/?
UNC-Wilmington - 1989-?/2006
Franklin and Marshall - 1982-200?/2007
University of Missouri - 1910-?/1998

According to this Wikipedia page, the Mizzou chapter underwent revitalization in 1998.

Dates
 

Here are the ones you had missing:

Missouri 1910-1998/1998
Washington State - 1945-1985/1990
UNC-Wilmington - 1989-2005/2006
Franklin and Marshall - 1982-2003/2007

Bentley is Zeta Rho not Sigma Rho. Not my chapter but one of my favorites!

Knew that!
 

I knew and have that in my list!!!! I just have to get my brain to work instead of being on vacation some of the time!!! Thanks for keeping me on my toes. Guess I was doing some wishful thinking that we were on the Sigma list of chapters!

LOL getting closer every year!

Oklahoma City University - Delta Delta Chapter
 

Q - 36; M - 36
Campus Total - 96
AP Size - 103

The Omicron chapter at Mizzou recolonized in 1998. They never went off campus (recolonizing in the spring and participating in recruitment in the fall), so I don't really know if there needs to be a slash 1910-1998/1998- present or not (I do know that they celebrated a centennial in 2010, so they consider themselves to have been on campus the entire time.
Also, Quota at Mizzou was 86 this year.

I really like the girls of this sorority so far, but I do not think I will get a bid. Like I said, it is very competitive at my college because it is Greek oriented. Most of the girls are fighting to get a bid from either Alpha Phi, Pi Beta Phi, or Alpha Chi Omega. There is no in between for them; those three houses are it and what most girls are shooting for. I do not think I can compete, so I've already crossed them off my list. I know I'd be better off in Alpha Epsilon Phi anyway.

Another crash-

Northern Arizona
Quota 47
Alpha Phi 53

First formal recruitment! Congrats!
