From 1888 to 1892, Annie Hubel Andrews was postmistress of the Zion Post Office (COM102) at Orange Grove House of Refuge No. 3, near present Delray Beach. Annie was married to Steven N. Andrews, the second and last keeper of the house; having the office meant her husband had to leave her alone to pick up mail at Hypoluxo. Charles W. “Charlie” Pierce wrote, “The office of Zion must have been the smallest in the United States. … [Steven and his wife] were the only patrons, there was absolutely no one else.”
