SOUTH PORTLAND — Sharon Brasier, 66, died July 3 at Maine Medical Center in Portland after a prolonged struggle with alpha-1 anti-trypsin deficiency, a genetic condition.

She was born in Portland on Nov. 1, 1947, to John and Hazel Jameyson, and was a lifelong resident of South Portland.

Brasier graduated from South Portland High School in 1966, and received an associate’s degree from Westbrook College in 1968. On Dec. 20, 1969, she married Jeffrey T. Brasier, and the couple raised two children, Eric and Ellen.

Brasier worked as an administrative assistant for Maine Medical Center, a personnel manager for Deering Ice Cream, and an office manager for South Portland High School before retiring in 1998 due to illness.

She was an active member of St. Alban’s Episcopal Church in Cape Elizabeth. In her time at the church, she served as a lay reader, a chalice bearer, and a member of the vestry and of the Altar Guild.

The role in which she took most pride was that of a mother. As a “swim mom,” she cheered on her children during each race, saying she swam each stroke with them. When she wasn’t cheering, she was working behind the scenes as a member of the South Portland Swimming and Diving Booster Club.

In 2001, Brasier received a lung transplant, providing her a new lease on life and the opportunity to see her children marry and have their own children. In 2012, she received a kidney transplant, which saved her life again, and gave her two more years with her family.

Brasier was predeceased by her husband, Jeffrey, in 2006.

She is survived by her son Eric, his wife, Tracey, and their son Jameyson, all of Eddington; and her daughter Ellen Benson, her husband, Brian, and their two children, Liam and Nora, all of South Portland.

Survivors also include her brother, Gale Jameyson, of Amelia Island, Florida; sisters-in-law Judy Soule, of Poland, and Sue Larrabee and her husband, Harold, of Cumberland; brother-in-law Stephen Brasier and his wife, Clementine, of North Windham; many nieces and nephews; and close friends George and Rosemary Skillin, of Gorham, Rick and Donna Angell, of Gorham, and Lois Willis, of Falmouth.

The family would like to thank the doctors and nurses who cared for Brasier, especially Dr. Stephen Mette, who initially diagnosed her condition; the organ transplant teams at Massachusetts General Hospital and Maine Medical Center; and the many friends and family who provided transportation and company for her appointments in Boston.

A service with Holy Eucharist was scheduled for Thursday, July 10, at 11 a.m., at Cathedral Church of St. Luke, 143 State St., Portland. Burial will be at a later date.

In lieu of flowers, donations may be made to the New England Organ Bank, 60 First St., Waltham, MA 02451.
