The history of the last name Glasco

The surname Glasco is believed to have originated in Scotland, likely in the late medieval period around the 13th or 14th century. It is thought to be a variant spelling of the place name Glasgow, which itself derives from the Brittonic Celtic words "glas" meaning "green" and "cau" meaning "hollow" or "ravine".

The earliest recorded instances of the Glasco surname appear in Scottish records from the 15th and 16th centuries, often spelled as Glasgo, Glascow, or similar variations. It is possible that the name was initially borne by individuals who hailed from the city of Glasgow or the surrounding area.

In the Domesday Book of 1086, a survey of land ownership in England commissioned by William the Conqueror, there are no direct references to the Glasco surname. However, there are mentions of the settlement of "Greslic" in Staffordshire, which may have been an early form of the place name Glasgow.

One of the earliest known bearers of the Glasco surname was John Glasco, a merchant and burgess of Edinburgh, who was recorded in documents from the late 15th century. Another early example is Robert Glasco, a Scottish cleric who served as the Provost of the Collegiate Church of St. Mary's in Biggar in the early 16th century.

In the 17th century, a notable figure with the Glasco surname was James Glasco, a Scottish minister and author who was born in 1612 and published works on theology and ecclesiastical history. Around the same time, there was also a John Glasco who served as the Provost of Abernethy in Perthshire in the 1660s.

Moving into the 18th century, one prominent individual with the Glasco surname was Alexander Glasco, a Scottish merchant and landowner who was born in 1718 and owned estates in Renfrewshire. Another was William Glasco, a Scottish soldier who fought in the Jacobite Rising of 1745 and was later executed for his involvement.

As the Glasco surname spread beyond Scotland, it also took on various spellings and variations in other regions, such as Glascoe and Glascow in England and Glasco or Glascoe in parts of North America where Scottish immigrants settled.
