Between 1934 and 2024, Three Rivers Birding was known as Stockbridge Audubon Society in honor of Charles Stockbridge, who was a nationally known as an ornithologist. He was born January 16, 1856, to parents who had come on the newly opened Wabash and Erie Canal.  His father owned one of the first bookstores in Fort Wayne, Indiana and Charles worked in the bookstore before becoming a letter carrier in Fort Wayne for many years. He lived at 2323 Webster St. and was married 55 years to Ada Ashley. 

He served as president of the Fort Wayne Audubon Society and gave many talks on bird life before clubs, schools, Boy Scouts, and the Historical Society. He is believed to be one of the two observers on the first Fort Wayne Christmas Count, in 1910. He sent migration reports to the state and national governments, and had a fine collection of bird specimens.

He retired from the post office at age 65, and then, with his two daughters, operated the Fort Wayne Baby Chick Hatchery until his death on March 4, 1934. He was survived by his wife, Ada, daughters Alathea and Mary, and son Willard. His bird collection was moved from the public library to the Swinney Homestead and later they went to Earlham College. He is buried in Lindenwood Cemetery, section H near where we look for white-winged crossbills in the tall hemlocks. Ed and Cynthia Powers found the large gray granite family marker, over the hill from the prominent one for Henry Rudisill.
