St. Ann Catholic Church has been in existence for 96 years. When the parish was created in 1914, there were many Catholic families scattered over the central part of Evangeline Parish, most of them around the town of Mamou, which had been incorporated in 1911. The majority were farmers or in farm related businesses.

Today, about 1,035 families make up the Catholic community of St. Ann parish which includes Holy Spirit Chapel in Vidrine. Many are still farmers or in farm related businesses, though not as many as in past years. Due to economic conditions and the emergence of the oil industry in the area and offshore, many parishioners work in that industry. A large hospital complex in Mamou also provides local jobs.
