By far, the most interesting feature in this graveyard – and surely one of the most remarkable in any Ulster graveyard – is the mausoleum erected in memory of the Stephenson family. It has been likened to the Taj Mahal and was possibly inspired by the Indian associations of one of those interred in it. It was built of Tardree stone in the late 1830s at a cost of £1,300, paid for by Dr Samuel Martin Stephenson.
He was born at Straidballymorris, near Templepatrick, in 1742, the son of James Stephenson, a farmer, and his wife Margaret Martin. After completing his studies at Glasgow University, he was ordained minister of Greyabbey Presbyterian Church in 1774. While he was minister of Greyabbey he studied medicine and in 1785 left the congregation to become a full time doctor.
Samuel Stephenson died in 1833 aged 91 after a distinguished career in medicine. His son Samuel Martin Stephenson junior was Superintendent Surgeon of the Madras Presidency; he died in 1834 aged 50. The iron door of the mausoleum bears the legend, ‘Rowan, Doagh, 1837’. This refers to John Rowan who operated the forge in Doagh.
