MARGARET KOOK-SUN CHAN Dec. 24, 1946 – Oct. 24, 2019

Margaret Kook-Sun Chan, 72, of Rancho Cucamonga, CA, formerly of Los Alamos, NM, died peacefully on Thursday, October 24th at City of Hope Hospital in Southern California after a long but courageous battle with cancer.

Born in Guangzhou, China in 1946, she moved to Hong Kong and graduated from the Chinese University of HK. She then immigrated to the United States and received a Master’s degree from the University of Pittsburgh in 1975. There she met her loving husband and started a family.

In her 40’s, she returned to school and obtained a degree in computer science from the “Women in Science” program from the University of New Mexico, Los Alamos. She worked as a computer professional at Los Alamos National Laboratory until her retirement in 2009.

Margaret was known for her caring and generous nature, and for being the soul of the Chan family. She was a loving mother and wife. She enjoyed spending her time on crafts, a quality that she has passed down to her children and grandchildren. She drew, worked with ceramics, sewed and knitted. But her best craft was her cooking, which was renowned by her family and friends.

Margaret was an active member of the Immaculate Heart of Mary Catholic Church in Los Alamos and later of St. Peter and St. Paul Catholic Church in Alta Loma, CA. She used her talents as part of parish ministry. Though she was sick, she always thought of others before herself and knitted prayer shawls and made rosaries to give hope to others who were ill.

Margaret was also fun loving and lived life to the fullest. She has lived in Hong Kong, Pittsburgh, Canada, New Mexico and California. In the past few years, she became a world traveler and adventured with her husband, family, and friends to the Holy land, Fatima, South America and all over Europe.

She will be lovingly remembered by her husband of 46 years, Dominic Chan, and her two sons and spouses: Joseph, Janet, Jeffrey and Teresa. She is also survived by her three adoring grandchildren, Carter, Emily and Katie, and her dog Bella.

A memorial service honoring the life of Margaret will be held on Saturday, November 9th at St Peter and St Paul Catholic Church in Alta Loma, CA. Rosary Service will begin at 12:30 p.m., Mass at 1:00 p.m. and a Reception and Memorial at 2:00 p.m.

The Chan family has designated St. Peter & St Paul Parish for memorial contributions. Please note in your donation, in honor of Margaret Chan.
