Ellin Berlin, a debutante of the Roaring Twenties who scandalized her father and risked her inheritance to marry songwriter Irving Berlin, died Friday at Doctors Hospital. She was 85.

The death followed a series of strokes that forced Mrs. Berlin to be taken from the couple's stylish town house on Manhattan's East Side, where they lived as virtual recluses for the past decade.Mrs. Berlin was herself a writer, publishing the last of four novels, "The Best of Families," in 1970. Her short stories were published in The Saturday Evening Post, The Ladies' Home Journal and other magazines beginning in 1933 and she also contributed articles to The New Yorker before her marriage.

The couple's only son, Irving Berlin Jr., died in infancy. In addition to her husband, Mrs. Berlin is survived by the couple's three daughters, a brother, nine grandchildren and a great-grandchild.
