Descendants of the of Edgar Bayard Riley will give a presentation on the Rehoboth Beach of the early 20th century at 7 p.m. Aug. 3 at the Rehoboth Beach Museum, 511 Rehoboth Ave.

Seth Melchert and his family, descendants of Edgar Bayard Riley and William Herman Riley, will share memories of a time when Highway One was two lanes and called State Road 14.

Edgar Riley, a Wilmington hardware store owner purchased property between Columbia and Henlopen avenues and built houses and a cottage sometime at the beginning of the 20th century. He was mayor of Rehoboth Beach from 1911 to 1912.

Melchert has organized old family photos to create a presentation about what life was like when the Rileys first came to the area. One of first buildings was believed to be used as a hunting lodge. Other members of the family will share reminiscences and answer questions.

The program is free for historical society members. A $5 donation is suggested for nonmembers. Reservations are required to 227-7310.
