Cynthia Ziegler, a descendant of baking powder magnate William Ziegler, has listed Hay Island in Darien, Connecticut, for $35 million. The 18-acre private island, accessible via a gated causeway, features an 8,700-square-foot colonial home with six bedrooms, seven bathrooms, six fireplaces, a two-bedroom guest house, an infinity-edge pool, a spa, and a private dock. Sotheby’s International Realty’s Lesle McElwreath holds the listing. This sale marks the Zieglers’ final property in Darien after selling Ziegler Farm for $57.5 million in late 2023 and the town purchasing Great Island for $85 million.
