The history of the last name Hemlock

The surname Hemlock is believed to have originated in England during the medieval period. It is thought to have derived from the Old English words "hemel" and "leac," which together mean "stalk leek" or "hollow leek." This likely referred to a hollow or depressed area where the leek plant grew abundantly.

During the Middle Ages, many people adopted surnames based on their occupations, physical characteristics, or the places they lived. Hemlock may have initially been a descriptive name given to someone who lived near a patch of hemlock plants or a location known for these plants.

One of the earliest recorded instances of the name Hemlock can be found in the Subsidy Rolls of Yorkshire from the 14th century, where a John Hemlok is mentioned. This provides evidence that the surname was in use by that time.

In the 16th century, the Hemlock surname appeared in various parish records across England. For example, a William Hemlock was listed in the Parish Registers of St. Michael's Church in Somerset in 1576.
