Margaret “Peggy” Cullerton Hosty, 75, of Westchester, formerly of River Forest, died on Aug. 1, 2025. Born on March 22, 1950 in Chicago and raised in Winfield. She was a graduate of Loyola University and earned a master’s degree from DePaul University. A scholar of the English language, she passed her skills to her children, proofreading their high school papers, regularly correcting their grammar and always believing in their potential to succeed. She valued her experience at Loyola University’s Rome Center and provided both of her children with the same life-changing opportunity to study abroad.
She knew a lot of people and built a wide community of loyal friends, nurturing close-knit relationships within her strong Irish family and beyond.
She served as matriarch to her eight siblings and “Boss of the Big House” at the family compound on Lake Michigan. Her last visit to Michigan was spent playing on the beach with her great nephew and nieces with whom she had a special bond, ensuring she made a lasting impression on the fifth generation of Cullerton lake-goers.
She could be counted on to add more fun to any celebration and support during difficult times. She was so well known for her dip that she always kept the main ingredient stocked in her fridge in case of emergency.
She leaves a void at the center of her clan and her circle of friends. She will be sorely missed.
Peggy was the mother of Alice (Bob Kolada) and the late Robert Emmett Hosty Jr.; the sister of John (Pam) Cullerton II, Mary Carroll Durand, Alice (Jim) Corcoran, Tom (Susan) Cullerton, Trish (Mike) Lynch, Patrick (Faith) Cullerton, Maureen (Jim) Leffler and Michael (Kai) Cullerton; the daughter of the late Patricia (nee Tyrrell) and John ‘Jack’ Cullerton I; former spouse of the late Robert Emmett Hosty Sr.; and the aunt of 34 nieces and nephews and too many cousins to count.
Visitation will be held at 9 a.m. on Saturday, Aug. 16, immediately followed by a Celebration of Life Mass at 10 a.m. at St. Giles Parish Church, 1025 Columbian Ave., Oak Park. Interment private.
In lieu of flowers, please consider a memorial donation to Misercordia (6300 N. Ridge Ave. Chicago, IL 60660) or the charity of your choice.
