Of Pittsburgh, PA, age 68 years young, went peacefully on December 23, 2019, to be with her brother, Bill Fogle, and parents, William and Mary Fogle, among others, in heaven, after a sudden but prolonged medical battle. Mary Lou was known for her sarcasm and wit as well as her insatiable appetite for knitting. She thoroughly enjoyed life, especially spending time with her beloved husband of 47 years, David Rattay, and her children, David W. (Kristine) Rattay and Christina Ramsey. Her greatest joy though, came from her five grandchildren; her "bonus" kids, Michael Ramsey, Jr. along with Sarah and Nicole Ekmekchyan, and her "puppies", David A. Rattay and Colten Ramsey. She is also survived by her brother, Larry (Linda) Fogle; sisters-in-law, Bernie Fogle, Kathy (John) McNally; brother-in-law, Bob (Linda) Rattay; "like-a-sister" Cindy (Carl) Dingus; numerous cousins, nieces and nephews, friends, and Pat Catan co-workers.
