Isabell Upton, a native of the Baltimore area who worked many years for the E. I. du Pont de Nemours & Co., died Friday at a nursing home in Akron, Pa., after a long illness.
Graveside services for Mrs. Upton, who was 81 and had lived since 1989 in New Holland, Pa., were held Tuesday at the Friendship Cemetery at Baltimore-Washington International Airport.
She retired in 1974 after making maps and charts for Du Pont for more than 20 years.
The former Isabell Clark moved from the Baltimore area to Wilmington in 1946. Her husband, A. Carroll Upton, died in 1952.
She is survived by a son, Allan R. Upton of Shartlesville, Pa.; a sister, Naomi C. Clarke of New Holland; seven grandchildren; and 11 great-grandchildren.
