Whatever their relationship is, Andie and Jenna are not biologically mother and daughter. From a 2007 blog about Jenna's recruitment into the sorority she belongs to:
This year's Recruitment was especially exciting for me because Helen Kolp's* great-granddaughter, Ann Kolp Roche's* granddaughter, Missie Roche Sykes' daughter, and Mimi Roche Cotter's niece, Jennifer Ann (Jenna) Sykes from Niceville, Florida was one of the "Crown Girls." I had Missie bring Jenna to Athens for Gamma Pi's Diamond Challenge in the spring, and she fit in like a bug in a rug - they loved her right away!!! Good move, Mamas, if you have Potential New Members. When the girls on the inside know you, you stand a much better chance - no matter how many references you have!
