The surname Blackney is of English origin, and it can be traced back to the late 16th century. It is believed to have originated from the villages of Blackney and Blackney Green in Somerset, England. These place names are thought to derive from the Old English words "blaec" and "ey," which together mean "black island" or "dark island."
The earliest recorded instance of the surname Blackney appears in the parish records of St. Mary's Church in Taunton, Somerset, in the year 1592. The record mentions a John Blackney, who was born in the nearby village of Blackney Green.
In the 17th century, the Blackney family was well-established in the Somerset area, with several members holding prominent positions in the local community. One notable figure was William Blackney (1625-1698), who served as the mayor of Taunton in 1675.
During the 18th and 19th centuries, the Blackney surname spread to other parts of England, particularly to the neighboring counties of Devon and Dorset. In 1792, a Thomas Blackney (1758-1821) was born in the village of Blackney, Somerset. He later became a successful merchant and businessman in Bristol.
Another significant bearer of the Blackney name was Reverend John Blackney (1809-1879), an Anglican clergyman who served as the vicar of St. Peter's Church in Tiverton, Devon, from 1850 until his death.
In the 20th century, one of the most prominent individuals with the Blackney surname was Sir Richard Blackney (1905-1988), a British civil servant and diplomat. He served as the Ambassador to Yugoslavia from 1957 to 1961 and later held various other diplomatic positions.
It is worth noting that the Blackney surname has also been recorded with slight variations in spelling, such as Blackny, Blacknay, and Blacknee, particularly in older historical records.
