Most of Port O'Connor was built recently: 0.0% of its homes predate 1940 and the median home dates from 1992. Below: 3 old photos and papers, maps from 1952 on, and the census since 1980.
Port O'Connor was laid out in the late 19th century as a fishing settlement called "Alligator Head". As it grew in popularity with both permanent residents and tourists, the community took on more municipal characteristics, earning the formal designation finally in 1909 as the town site of Port O'Connor. It was named after its main landowner at the time, Thomas M. O'Connor, son of Thomas O'Connor, who owned 70,000 acres (280 km2). Aside from local cattle raising and fishing, the town was also a producer of figs and citrus fruit.
Its initial population growth spanned the years 1909 to 1919. Excursion trains ran on weekends to Port O'Connor, and an estimated 10,000 tourists came every summer.
