A memorial Mass for the Greenwell family and Mary Wallace Greenwell, who with her brother donated land for a state park intended primarily for the disabled, will be offered at noon Saturday at St. John's Roman Catholic Church in Hollywood, St. Mary's County.
Miss Greenwell, who was 92, died March 17 in Louisville, Ky., where she had lived in the Nazareth Home.
She and her brother, the late Philip Greenwell, donated Rosedale, their home on 177 acres overlooking the Patuxent River near Hollywood, to be developed into a park for the mentally and physically disabled.
Since the donation of the property two decades ago, Greenwell State Park was expanded to 600 acres. Last summer, a two-week summer camp for disabled children and young adults was inaugurated at the park.
One of six children of John Philip and Mary Estelle Cawood Greenwell of Stone's Wharf and Leonardtown, St. Mary's County, Miss Greenwell was the last surviving member of that family, which county land records mention as early as 1740.
Miss Greenwell was a lifetime companion to her brother, Philip, and a secretary for his business, Eastern Outdoor Advertising Co. They had traveled together around the world before his death in 1986.
Another brother, the late Rev. Hezekiah Greenwell, S.J., had been vice rector of Woodstock College and first pastor of Our Lady of the Wayside Church near Chaptico.
Two of her late sisters -- Sister Mary Angelica Greenwell and Sister Mary Estelle Greenwell -- were nuns with the order of the Sisters of Charity of Nazareth, and another sister, Jane Evangeline Greenwell, was retarded and died as a young woman in 1925.
Miss Greenwell graduated from St. Mary's Academy in Leonardtown in 1916 and from Manhattanville College in New York in 1920.
She was a member of the Colonial Dames of America.
The family trustee suggested memorial donations to the Sisters of Charity of Nazareth, St. Mary's Convent, Leonardtown 20650.
