The history of the last name Monan

The surname Monan has its roots in the Gaelic language and is believed to have originated in Scotland during the medieval period. It is derived from the Gaelic word "monadh," which means "hill" or "mountain," suggesting that the name may have been given to someone who lived near or on a hill or mountainous region.

One of the earliest recorded instances of the name Monan can be found in the Ragman Rolls of 1296, which documented the names of Scottish noblemen who swore fealty to King Edward I of England. This historical document mentions a "Gillebride Monath," which is likely an early variant spelling of the name.

During the 16th and 17th centuries, the name Monan was prevalent in the Scottish Highlands, particularly in the regions of Argyll and Inverness-shire. Historical records from this period show variations in the spelling, such as "Monane," "Monand," and "Monath."

Notable individuals with the surname Monan include Sir John Monan (1560-1631), a Scottish laird and landowner from Argyll, who was known for his involvement in the Clan feuds of the time. Another prominent figure was Archibald Monan (1685-1756), a Scottish merchant and trader who established trading routes between Scotland and the American colonies.

In the 18th century, the Monan family had a strong presence in the Outer Hebrides, particularly on the Isle of Lewis. Records from this period mention Angus Monan (1720-1792), a respected crofter and Elder of the Presbyterian Church in Stornoway.

As the Monan family spread across Scotland and beyond, the name evolved to include variations such as "Monahan" and "Monaghan," which are more commonly found in Ireland. One notable individual with this variant spelling was John Monaghan (1825-1899), a Scottish-born businessman and philanthropist who made his fortune in Australia.

Throughout history, the surname Monan has been associated with several place names in Scotland, such as Monan's Croft on the Isle of Skye and Monan's Hill in Aberdeenshire. These place names further reinforce the connection between the surname and its geographical origins.
