Hello bagpipe. Rev John is an ancestor of mine. I have been digging into the family's past for 40 years and have found that the written histories are a good starting point, but not necessarily 100% correct.
He was the son of John McLean of Grishipol, a gentleman of Clan McLean of Coll.
The name has been standardised to 'Maclean' for anyone of any section of the clan by writers and historians, but it was only the last Laird of Coll during the 19th century that adopted that spelling. John used McLean until he obtained his M.A. when he added the suffix 'e', as was traditional for graduates to become Rev. John McLeane. He graduated as Master of Arts M.A. Glasgow University on the 15th June 1672.
He became a professional soldier before taking up the Parish of Kilmory on the Isle of Arran.
About 1785 he married Annabelle McNeil of the Losset family. They had two daughters Margaret and Abigail McLeane. The family moved to Ulster after John was outed from the Church.
He became minister at Coleraine, then in 1701 under the patronage of Viscount Masserenne, he gained Antrim Parish while also holding Drummaul Parish.
His first wife Annabelle had died by this time, as the Christenings of his children to his 2nd wife Annie Cubbage start appearing in the Antrim Parish register.

He died whilst travelling in 1729 at County Antrim, leaving his son to clear his debts.
His eldest son John became Vicar of Billy in County Antrim. Another son Rev. James McLeane was incumbent of the Island of Rathlin, 1740 -1747.
His brother Lauchlan McLean of Grishipol became joint Bailie of Tiree along with Hugh MacLean of the Boreray family for Maclean of Duart. Lauchlan kept this position under Argylls takeover of the Maclean lands with resulting consequences.
Some books covering the family include 'From Clan to Regiment' Maclean-Bristol, and various Maclean Clan histories.
