I am attempting to piece together of this family from the late 18th century - present. From various sources, I have established the existence of the following individuals: John Templeton (born c1785) married Eleanor Vint. Their daughter, Susanna, married Samuel Leeburn in 1846. The aforementioned, John Templeton, may have lived in Carntall, Ballylinney. Secondly, a Samuel Templeton (born c1795), (spouse unknown). They had a son, William, who married Isabella Piercy in 1859. Samuel (born c1795), may have lived in Lisnalinchy, Ballylinney. William and Isabella had a son, William (born 1865), who married Margaret Campbell in 1888. I know that one of their sons, John Campbell Templeton (1894-1972) married Mary Jane McGladdery in 1925. John (1894-1972) had two brothers, William (born 1892) and Robert (born 1902/03). Their sisters were: Elizabeth Ann, Hannah Florence, Mary, Margaret Louisa and Harriet Irene.
Thirdly, Samuel Templeton (born c1780), (spouse unknown), had two sons (I think). Alexander Templeton (1811-72) married Elizabeth Curley in 1855. Their family were: Samuel, John, Alexander and Susan. Then, Samuel Templeton (1808-70), married Margaret Auld. Their family were: Margaret, Eliza, Robert, John, James and Mary. Samuel, (born c1780) may have lived in Jordanstown, Carnmoney, and is possibly the father of a James Templeton (born 1819), who married Eliza Dulighan in 1845. Their family were: John, Joseph, Martha and Thomas.
Fourthly, Joseph Templeton (born c1796), (spouse unknown). He had a daughter, Eliza Jane (born 1826), who married, Alexander Kelso in 1851. Joseph, (born c1796), may have resided in Mallusk, and I think he was also the father of (1) Joseph Templeton (1828-77), who married Mary Greer in 1870. Their family were: Elizabeth, Louisa and Agnes. (2) Robert Templeton (1835-1900) who married Hannah Carruth in 1866. Their family were: Annie, Joseph, Thomas, Mary and Margaret.
Fifthly, James Templeton married ? McConnell, around 1862, and had several daughters, and a son named John (born: c1877). John, was recorded in the 1911 Census, residing with his unmarried Aunt, in Carnmoney.
Finally, a John Templeton, (born c1800), (spouse unknown), had a daughter, Mary Eliza who married Luke Hope in 1853. John (born c1780) may have lived in Monkstown, Carnmoney.
