Lucille F. McMahon, 91

Lucille F. McMahon, a lifelong Sag Harbor resident known for tending particularly lovely gardens, died in her sleep at home on July 5 at the age of 91, one week before her 92nd birthday.

One of her daughters, Patricia Mongiello of East Quogue, said her mother maintained a very active lifestyle until recently, still cooking for herself and cleaning her house. She said her mother loved taking walks and cultivating her garden.

“People would stop and look at her yard,” Ms. Mongiello said. “She cut her own lawn up until about a year and a half ago, and took a lot of pride in her home.” She cherished her children, grandchildren, and great-grandchildren, her daughter said. “That was her life.”

Mrs. McMahon was born in Southampton on July 12, 1924, one of six children of Michael Ficorilli and the former Agnes Matoccia, who had also been born in the village. She grew up in a house on Oakland Avenue and graduated from Pierson High School in 1942.

Three years later she married Raymond McMahon, then a chief engineer in the Merchant Marine. The family moved to Franklin Avenue in 1960. Mrs. McMahon became a single mother after her husband died in 1961, working for the Long Island Lighting Company while raising three daughters. She later met George Thompson of Mattituck and the two maintained a close relationship, though they never married. Mr. Thompson died in 2006.

Mrs. McMahon was a longtime member of St. Andrew’s Catholic Church in Sag Harbor. She loved the village most in the wintertime, Ms. Mongiello said, “when it was quiet and peaceful. You could walk to town and you knew everybody. That’s the Sag Harbor that she loved, the quaintness of it.”

In addition to Ms. Mongiello, she leaves two other daughters, Marilyn Stanco of Setauket and JoAnn Holland of Las Vegas. She is also survived by six grandchildren and 10 great-grandchildren.

Visiting hours for Mrs. McMahon were held on July 7 at the Yardley and Pino Funeral Home in Sag Harbor. Her funeral was the next day at St. Andrew’s, followed by burial in the church cemetery. The family has suggested memorial donations to Memorial Sloan-Kettering Cancer Center, online at giving.mskcc. org.
