Marrian D. Curran Sr., 78, a retired D.C. elevator inspector and a former riding instructor, master of fox bounds and horse breeder, died Thursday at Washington Hospital Center of complications following surgery.

Mr. Curran retired as the city's chief elevator inspector in 1955 after 29 years as an inspector.

He was master of fox hounds of the Goshen Hunt in Montgomery County from 1959 to 1969. Before that he had owned his own pack and had been an acting master of fox hounds of the old Redland Hunt.

He bred and raised thoroughbred horses including a recent three states stakes winner, Jimminetti.

Mr. Curran was born in Washington and reared in Montgomery County.

He ran his own riding school in Montgomery County during the 1930s and early 1940s, where he taught students from Trinity College and Georgetown University.

He had been chief of the Kensington Volunteer Fire Department from 1927 to 1933. He was a charter member of the Rosensteel chapter of the Knights of Columbus and belonged to St. Martin's Catholic Church in Gaithersburg.

He is survived by his wife, the former Nellie M. Carlin of the home, Tall Grass, in Gaithersburg: two sons Marrian D. Jr., of Manor Club Md., and J. Carroll of Goshen Md., a daughter, E. June Brathover, of Rockville; 15 granchildren, and eight great-grandchildern.
