History The Ais people, attracted to the mouth of Turkey Creek at the Indian River by freshwater springs, fish, oysters, and wildlife, are thought to have been the first inhabitants in the Palm Bay area. The earliest place names for this area on early maps of the late 1700s were Turkey Creek, Elbow Creek and Crane Creek. An 1870 map of the Indian River by John Andrew Bostrom shows the area void of any settlements within about 15 miles of Turkey Creek. The first prominent European-American settler was John Tillman in the late 1870s. Tillman's wharf marked the mouth of Turkey Creek at what became known as Palm Bay on the Indian River. By the late 1880s, Tillman was operating a profitable orange and banana grove on the north shore of the creek. He had the most notable banana grove on the Indian River. Tillman's wharf also attracted settlers, as it was a steamboat stop. By the mid-nineteenth century, there was a lumber operation, orange groves, and packing house. Growth was slow until the arrival of the railroad in 1894. Then goods were brought in and produce was shipped to market faster. 1900s Between 1910 and 1914, a land company known as the Indian River Catholic Colony became established at Tillman. Attempting to grow two crops a season, farmers quickly depleted the soil, and the colony failed. Those remaining built St. Joseph's Church on Miller Street, the oldest building still standing. In the 1920s, the city was renamed as Palm Bay, after the bay bordered with sabal palm trees known as Palm Bay, located at the mouth of Turkey Creek. A group of Tillman businessmen established the Melbourne-Tillman Drainage District, and issued $1.5 million worth of bonds. Starting in 1922, a grid of 80 canals was
