Rosemarie J. Horstman, 88, of Pymatuning Township, died Sunday, September 11, 2016, in her home surrounded by her family after a lengthy struggle with Alzheimer’s disease. She battled the illness with integrity, fortitude and grace and will be missed dearly by family and friends.

Rosemarie was born November 6, 1927, in Sharon, a daughter of John and Mary Tomko Soos. She graduated from Sharpsville High School in 1945. She worked at Westinghouse Electric in Sharon, PA and later at Reynolds High School, where she retired in 1993 after 23 years of service.

She married Clemens Horstman on August 22, 1953.  She devoted her life to raising her children.

Following her husband’s death on January 1, 1981, she became a very significant part of each of her grandchildren’s young lives supporting them in many unselfish ways. She also remained very close to her husband’s family and was active in her catholic faith as a long time member of St Michael’s Catholic Church. She enjoyed time with her lifelong Club Girls going to polka dances and playing cards.

In addition to her parents and her husband, she was preceded in death by a sister Dorothy Burnett and a brother Coleman Soos, sister-in-law Velma Perdian and her husband Alphonse, and many Tomko aunts, uncles and cousins.

Rosemarie is survived by her five children: Howard and his wife Nancy of Hummelstown, PA; Dan of Greenville, PA; Joyce of Greenville, who was her caretaker; Theresa Horstman and her husband Ron Cole of Hermitage, PA; and Mark and his wife Karen of Erie, PA. She also is survived by eight grandchildren: Dan Horstman of Denver, CO, Lexi Horstman of Baltimore, MD, Matthew Clune and his wife Sandra of Sharpsville, Noah Cole of Hermitage, Nelson and Michael Horstman of Greenville,  Julia and Jon Horstman of Erie; and a great grandson Lucas Clune.  She is further survived by a brother Phillip Soos of Transfer and sister-in-law Leota Horstman of Mercer.

Memorials may be made to St Michael’s Roman Catholic Church, 85 N. High St., Greenville, PA or the Sister of Charity of Seton Hill, 144 DePaul Center Rd., Greensburg, PA 15601.

    I enjoyed the easter egg hunt at her house when our kids were young, and the times I would see Rosemarie with Joyce or Theresa. May God bless your family with much support, loving memories, and ongoing solidarity in your beautiful family.
