The earliest Episcopal/Anglican worship in western Connecticut began in the town of Kent in 1763, served by itinerant missionary priests ordained in England. They worshipped in a now lost St. Thomas’s Church built on Kent Plain sometime between 1768 and 1772. St. Andrew’s Episcopal Parish was first organized as St John’s Parish in 1806. In 1819, Reverend George B. Andrews took charge of the Episcopal congregations in both Kent and nearby Marbledale (in New Preston). He was soon serving congregations in Caanan and Salisbury as well. His wealthy wife contributed greatly to funding the erection of churches in these parishes. The current church building in Kent, located at the corner of modern Routes 7 and 341, was constructed in 1826 of fieldstone in the Gothic Revival style. In gratitude to Rev. and Mrs. Andrews, the parish was renamed from St. John’s to St. Andrew’s.
In the 1870s the chancel and sacristy were added to the west side of the building and the bell tower’s original crenelated top was replaced with a pointed steeple. The church underwent major renovations in 2014.
Marbledale is in the Census district of New Preston, but it is a village in the town of Washington, as is New Preston.
