Helen L. "Susie" Swann, an interior decorator who was a co-founder of Swann-Hall Associates, died Sunday of cardiac arrhythmia at her Murray Hill home. She was 69.
Helen Leigh Snodgrass, the daughter of a Baltimore & Ohio Railroad executive and a homemaker, was born in Washington and moved with her family in 1949 to Guilford.
After graduating in 1949 from Bryn Mawr School, she attended Manhattanville College and Goucher before marrying Mason Swann, a business executive, in 1962.
After working with several interior designers, she co-founded Swann-Hall Associates in 1983 and served as president. The interior decorating firm did both residential and commercial work, family members said.
Some of the firm's work included the L'Hirondelle Club in Ruxton and Caves Valley Golf Club.
Mrs. Swann, who retired several years ago, enjoyed spending summers in Cape May, N.J. She was also an avid gardener.
She was a member of the L'Hirondelle Club and was a former member of the Junior League of Baltimore and the Maryland House and Garden Pilgrimage.
She attended the Episcopal Church of the Redeemer, 5603 N. Charles St., where a memorial service will be held at 11 a.m. Saturday.
In addition to her husband, who is retired from Stump, Harvey & Cook, Mrs. Swann is survived by two daughters, Leigh S. Halstad of Westminster and Brooke S. Delmar of Wallingford, Pa.; a brother, Francis R. "Tony" Snodgrass of Washington; and five grandchildren.
