Carol Lider Thrope-Of Arlington left us too soon on October 26, 2022, a month shy of her 71st birthday after a long bout with the cruel ravages of Lewy Body dementia and Parkinson’s. Loving wife, mother, grandmother, sister, aunt, and cousin, Carol was an energetic free spirit whose bonds with family and enduring friendships enriched those who knew her. Working in the fields of adoption and senior care, she spent her social work career helping others from newborns to the very old. She was a passionate and knowledgeable bird watcher and an enthusiastic runner. After years as a single parent with her daughter Kendra, she met Marty at a square dance at the VFW in Cambridge, and they married a year later. With deep respect for the memory of Marty’s first wife who had died five years earlier, Carol embraced as her own his young children Sam and Juliana, and she and Marty together built a family, first with the three children they brought to the marriage and then with their “ours” daughter Charlene. Carol was born in Boston in 1951, daughter of Edward and Dorothy (Yamins) Lider, and grew up in Newton. She received her BA degree from Brandeis University and her MSW degree from California State University Sacramento. She is survived by her husband of 30 years Martin; her children Kendra Lider-Johnson (Robert Wolfe), Samuel (Esther Rachow), Juliana Lewis (Thomas), and Charlene (Max Buckler); her grandchildren George, Elizabeth, Noam, Livia, Binah, Katelyn, Aiden, and Emerson; her sister Jane Goldman and her sister-in-law Lisa Lider; her sister-in-law Aileen Grossberg (Marc), her brother-in-law David Thrope (Janet); her Goldman nephews, and her Lider and Yamins cousins. She was predeceased by her parents, her brother Robert, Kendra’s father George Johnson, and her niece Stephanie Goldman. Her family wishes to acknowledge the entire staff at Belmont Manor and at Compassionate Care Hospice, as well as everyone else who was part of Carol’s care and the village of kind people who helped in ways great and small.
