Nellie Gorman, the daughter of a dairy broker and a homemaker, was born in Baltimore and raised in Roland Park.
After graduating in 1945 from Roland Park Country School, she received a bachelor's degree in English from Mount Holyoke College in South Hadley, Mass., in 1949. She earned a master's degree in education in 1968 from the Johns Hopkins University.
She taught briefly at Friends School and Roland Park Country School before her marriage in 1950 to John Richard Holland Jr., a banker with Baltimore Federal Savings & Loan.
After raising her family, she returned to the classroom in 1964 when she began teaching fourth-graders at Boys' Latin. She retired in 1983.
She had been a docent at the Maryland Historical Society and a member of the committee of the Maryland House and Garden Pilgrimage.
After she and her husband moved in 1998 to William Hill Manor, she volunteered at Easton Elementary School and Trinity Episcopal Cathedral.
Her first husband died in 2002. She was married in 2004 to businessman John M.R. Morton Jr., who died the next year. In 2007, she wed Robert D. Bartlett Jr., owner of an Oxford boatyard, who died the next year.
She maintained an interest in American history and historic preservation.
"When she was teaching, she enjoyed taking her students to Williamsburg every year," said a daughter, Elizabeth R. "Liz" Holland of Princess Anne.
A memorial service will be held at 1 p.m. Monday at Trinity Episcopal Cathedral, 314 North St., Easton.
Also surviving are a son, John R. Holland III of Chicago; and another daughter, Jane H. Smith of Elberta, Ala.
