The Seavers sold the cottage lot at 4 Standish to Ernest and Emma Marston of Westfield, NJ in September of 1923. Other lots were acquired from James Steele starting in 1925. The main house was built by the Marstons in 1924. After Charles and Hope Williams from Spuyten Duyvil, NY purchased the property in December of 1935, they expanded the main house, and added a carriage shed and stables in the garage for their horses. The Williams daughters, Sue and Edie, enjoyed horseback riding on the beach and around the Heights. A playhouse was also built later, to be used as a bunkroom for offspring and as a guest house. In November of 1951, the property passed to the Williams daughters, Susan Spencer Miller and Edith Dunham, and has been shared by the two families ever since.
