The history of the last name Blocksom

The surname BLOCKSOM has its origins in England, dating back to the late 16th century. It is believed to be derived from the Old English words "blocc" meaning a block or log of wood, and "sum" meaning a small piece or fragment. This suggests that the name may have originally referred to someone who worked with wood, such as a woodcutter or carpenter.

One of the earliest recorded instances of the name can be found in the parish records of St. Mary's Church in Islington, London, where a Thomas Blocksom was listed as being baptized in 1592. Another early record is from the Protestation Returns of 1641-1642, which document the names of individuals who swore allegiance to the Protestant faith during the English Civil War, and includes a John Blocksom from the county of Worcestershire.

By the 17th and 18th centuries, the name had spread to other parts of England, with various spellings such as Blocksam, Blocksom, and Bloxsom appearing in records. Notably, a William Blocksam was recorded as being a landowner in the village of Burley, in the county of Rutland, in the late 1600s.

One notable bearer of the name was Sir John Blocksom (1780-1856), a British naval officer who served in the Royal Navy during the Napoleonic Wars. He was present at the Battle of Trafalgar in 1805 and later rose to the rank of Admiral.

Another figure of historical significance was Mary Blocksom (1845-1923), an American educator and activist who worked to establish schools for African American children in the southern United States during the Reconstruction era following the American Civil War.

In the 19th century, the name also appears in historical records from the United States, with individuals such as James Blocksom (1817-1892), a farmer and landowner from Ohio, and William Blocksom (1839-1918), a Union soldier who fought in the American Civil War.

Throughout its history, the BLOCKSOM name has been closely associated with certain geographical areas, particularly the counties of Worcestershire, Rutland, and Lincolnshire in England, as well as parts of the American Midwest and South.
