Martha M. Cassidy, formerly of Southampton, died on November 13, at The Villa in Westhampton, an assisted living facility, where she had been a resident for the past four years. She was 86.
She was born on April 15, 1938, in Oceanside, New York, to Ralph and Dorotha (Parker) Mitchell, and grew up in Lynbrook. Her father was originally from Greenport, and she was a descendant of the Hallock family of the North Fork.
A gifted singer and piano player from an early age, she attended college at the Crane Conservatory in Potsdam, New York, where she excelled as a mezzo-soprano, performing as a soloist in many musical productions.
After graduating college, she married Kevin Edward Cassidy of Southampton, and they split their time between Northport and their home on Shinnecock Bay.
She worked as a music teacher for several years and attended Adelphi University, where she received her master’s degree in education. Following her teaching career, she worked at the Northport Public Library for more than 35 years.
In her spare time, she enjoyed reading and watching her beloved television westerns.
