Info on some lighthouses is hard to come by. Here is what I have on the Coxsackie Lighthouse.

The Coxsackie Lighthouse was established in 1830 and discontinued in 1939. It was replaced by a skeleton tower and then torn down. In 1890 a post light was erected about a half mile down river with the keeper being responsible for it. One day in 1923, Keeper McDougal was attending to the post light when it gave way, throwing him into the cold waters of the river. Fortunately for him, he was spotted by the captain of a Standard Oil tugboat clinging to the bow of his skiff and thus rescued from a certain death. The same ice jam which had caused damage to the Stuyvesant Lighthouse in 1902 also took its toll on the Coxsackie Light, taking out its north wall, some foundation stones and washing away the station's outhouses. Repairs were completed by that summer.

The lighthouse was located on Rattlesnake Island just north of Coxsackie.
