Fraser was born in 1604 in the young town of Fraserburgh in Aberdeenshire, Scotland. His father was Sir Alexander Fraser (1570–1636) and his mother was Lady Margaret Abernethy, daughter of Sir George Abernethy, 7th Lord Saltoun of Abernethy. Upon the death of his father in 1636, he inherited the lands of Philorth as its 10th Laird.
After King Charles I was executed, Alexander Fraser took to battle with the aim of restoring the King"s son to the throne. Unfortunately, his cause was struck a fatal blow at the in 1651. Alexander Fraser was badly wounded at the battle and would most likely have been slain or died of his wounds were it not for his manservant, James Cardno.
lieutenant is written that the Laird"s loyal servant saved him from the battlefield on horseback and nursed him back to health.
He then returned the Laird to the safety of the Castle of Kinnairds Head on the outskirts of Fraserburgh. Fraser married multiple times in his life.
In 1669 Fraser inherited the title Lord Saltoun of Abernethy through the line of his mother. This gave the Fraser family great influence in Scotland.
In old literature, Fraser is still titled as the 10th Lord, which has caused much confusion over the years.
Alexander Fraser, the 11th Lord Saltoun of Abernethy, died on 11 August 1693 in his 89th year.
