The Sinclaires of Newtownards and Belfast

As of April 1, 1954, Miss Mary Mulholland (b. about 1870-71) had in her possession the Mulholland Family Bible, which came from Belfast, Northern Ireland. It contained the names of Thomas Sinclaire’s 12 children and Henry Mulholland’s 14 children by his first wife (not recorded here) and those of his second wife – Georgina Sinclair. The Bible also contains the following inscription on a tombstone, which was in the cemetery adjoining St. George’s Church in Belfast. The cemetery is no longer there, some of the remains and tombstones having been removed to Clifton Street, Belfast:
“Here lieth the body of William Sinclaire of Belfast, Merchant, who departed this life on the 24th of December, in the year 1759, aged 80 years. Also his first wife, Jane Gregg, who died 11th of April, 1714, aged 32 years. Here also lieth the body of Jane Sinclaire, otherwise Scott, second wife of the above William Sinclaire, who died in the year 1760, aged 75 years. Also three of their younger children also John Sinclaire, Linen Draper, 2nd son of the above pair, is mentioned here. He died November 1769, aged 45 years. The body of Thomas Sinclaire, Merchant, eldest son of the above named William Sinclaire and Jane Sinclaire, is also interred here. He died the 8th of December 1798 aged 80 years.”

From The Sinclair Family of Belfast, N. Ireland and their Descendants 1660-1964, by Mrs St. Claire Lappe Daub (USA), 1954

It is possible that the first William Sinkler of Belfast was one of two sons of Alexander Sinkler of Newtownards, Co Down (1640/1650-c.1726), the other son being John Sinkler. Also see Alexander Sinclare of Dublin.
