My uncle-in-law (dad's sister's husband) is a
DTD from Westminster College in Missouri, but I didn't find that out 'til after I'd pledged.
My dad, his brother, his brother's wife, and my mom were all in local "literary societies" at Illinois College, and I knew that growing up. They were pretty big into the boozing and the hazing, I think, and both of my parents expressed concern when I pledged. I assured them that Kappa was different.
