Brooklyn was a Jessamine county community on the Kentucky River. It reached a population of close to 500 before it was destroyed by a late nineteenth century fire and flood. It was named for a Colonel Brook. A post office operated nearby at Cogar's Landing from 1854 until 1861. Thomas Cogar had a store, landing, and from 1845 until 1871 a ferry. (The first Brooklyn Bridge was built in 1871.) Todd's Ferry operated here sometime before Cogar's.
