Atlantic County, NJ
History
On February 7, 1837, the New Jersey legislature designated Atlantic County from Galloway, Hamilton, Weymouth, and Egg Harbor townships, choosing Mays Landing as the county seat. In the same year, the Board of Freeholders was established as the county government. As of the 1830 census, the townships making up Atlantic County only had a population of 8,164, making it the least populated New Jersey county. By that time, a continuous line of houses extended from Somers Point to Absecon.Mullica Township was established from Galloway Township in 1837. In 1852, Dr. Jonathan Pitney recommended Absecon Island as a health resort, and formed the Camden and Atlantic Railroad Company to construct the line from Camden to the coast. The company purchased land from Atlantic and Galloway Townships in 1853, then promoted and sold the lots. Atlantic City formed on May 1, 1854, in advance of the rail line opening on July 4 of that year. In 1858, Egg Harbor City was formed from portions of Galloway and Mullica townships. In 1866, Hammonton was founded from Hamilton and Mullica townships. A year later, portions of Hamilton Township split off to become Buena Vista Township. In 1872, Absecon was split from portions of Egg Harbor and Galloway townships. By 1885, more than half of the county's population lived in Atlantic City, and by 1910 this more than two-thirds of the county lived there.
