A Master Attendant at Thalassery Port, Sir Brennan was also a philanthropist. Upon reaching Thalassery following a shipwreck, he parted with all his savings to a poor fund. He died in 1859 CE and is buried at the church’s cemetery. It is the final resting place for many officials of the East India Company. The quaint church is simple and charming. It has been well-maintained and is a blend of Anglican and Gothic Revival styles. The state department of Archaeology renovated the church in 2009.
