Patricia Holmes-Mackay

Patricia Elizabeth Holmes-Mackay died on Aug. 12 at Mount Sinai Hospital in New York City of liver disease, the culmination of lifelong health problems. She was 50 years old.

Known as Trisha, Ms. Holmes-Mackay was a registered nurse who specialized in oncology, one of the very few certified in that medical specialty. She also used her nursing expertise as a consultant to law firms in wrongful death cases.

  Ms. Holmes-Mackay received a bachelor of science in nursing and a registered nursing degree at Mount Saint Mary College in Newburgh, N.Y. She worked at Boston Children’s Hospital from 1988 to 1992, at North Shore University Hospital in Manhasset from 1992 to 2004, and at Huntington Hospital the following year.

She was born on Oct. 28, 1966, in Southampton, the only child of the former Elizabeth Moses and Joseph Holmes of East Hampton, and grew up on Dayton Lane. Both parents died before her. She graduated from East Hampton High School before pursuing a nursing career. 

On April 20, 1996, she and Daniel P. Mackay of Farmingville were married at the Bridgehampton Community House, where a memorial will be held at her request on her birthday, Oct. 28, from 1 to 3 p.m. Her ashes will be dispersed at the Grand Wailea Resort in Maui, Hawaii.

In addition to her former husband, their daughter, Chloe Rose of East Moriches, whom she called My Sunshine, survives. The family has suggested donations for Chloe’s education to a gofundme account, found by searching “Chloe Mackay’ or “Trisha Mackay” at gofundme.com.
