Maria O. Brennan, an antiques dealer who owned the Grand Acquisitor in East Hampton for 20 years, died on Monday at Southampton Hospital. She was 74 and had been ill for a long time.
During her 40 years here, Ms. Brennan was active in the community, especially with the East Hampton Ladies Village Improvement Society. She was a former chairwoman of the society’s house committee.
“She loved her life in East Hampton, was a generous friend, and enjoyed the camaraderie of gathering together to celebrate life,” her family wrote. “Maria was strong, independent, and resilient.”
Ms. Brennan was born on Sept. 20, 1939, in West Palm Beach, Fla., to Manuel Ortuno and the former Mary Stender. Growing up, she lived in West Palm Beach, in Havana, and in New York City. She attended Holy Child Academy in New York and Marshall College in West Virginia before graduating with a B.A. and an M.F.A. with honors from Hunter College.
She was married on April 21, 1963, to John Brennan. They became year-round residents of East Hampton in 1974.
In addition to her husband, Ms. Brennan is survived by a brother, Manuel Ortuno of Texas.
A service will be held next Thursday at 11 a.m. at Most Holy Trinity Catholic Church in East Hampton. Burial will be private.
The family has suggested memorial contributions to East End Hospice, P.O. Box 1048, Westhampton Beach 11978.
