The Waln family were prominent Philadelphia Quakers who made a fortune in the 18th-century China Trade and descended from the original Pennsylvania settler Nicholas Waln. Joseph Waln Ryerss built Burholme as his summer house in 1859, and upon his death he left it to his son, Robert Waln Ryerss (1831-1896). Robert Waln Ryerss was a lawyer. He scandalized Philadelphia society by marrying his housekeeper, Mary Ann Reed, eight months before his death. Mary Ann remarried, and spent the rest of her life traveling to collect items for the museum now located in Ryerss' mansion. The Ryerss family papers, 1758-1931, contain documents, photographs, and volumes. Most of the collection relates to Robert W. Ryerss, his Waln antecedents, or his wife Mary Ann Reed (later Bawn).
