This is a small correction to the heading -
This was not John 'Og' McDonald - but John McDonald ( Iain MacEoghainn Oig)
It is thought that the family either originated in Glencoe, or was closely aligned with Glencoe and visiting the encampment on the night of the Massacre, escaping and resettling in Glenurquhart. The Clandonald Society on Skye believes the family may have originated in Glenmoriston and that is where the Glencoe ties were strongest
There is a birth record for twin daughters Ann and Helen (Ellen) born to John McDonald and his 2nd wife Margaret Grant at Drumnadrochit on 1 Jul 1772.
It is thought James was born in 1754 in Bunloit and Hugh (also known as Ewen, Evan, or Eoghann Mor) may have been born in 1764. Both James and Hugh were sons of john and Margaret.
A record exists for the birth of the eldest 2 sons of John Mcdonald and his 1st wife Janet or Jannet (surname unk). Duncan in 1740 at Loget and Alexander in 1742 at Loget, no record is known to exist for elder daughters Mary and Christy
From - Dr. William Mackay's Urquhart and Glenmoriston (1893) a short account is given of the Settlement in Nova Scotia. Dr. Mackay had written to Rev. D.B. Blair and Rev. A. Maclean Sinclair and from the information supplied by them this account was compiled. The manuscripts had been in the possession of Dr. Mackay's grandson, the late Mr. I.R. Mackay. Photocopies of which have been given to the Angus L. MacDonald Library, St. Francis Xavier University, Antigonish. Here is a list of natives of Urquhart and Glenmoriston who crossed the Atlantic to Nova Scotia, namely Pictou, East River (An Abhainn Mhor), Blue Mountain (A' Bheinne Ghorm) and Springville (Bail' an Fhuarain). Pictou Settlement now contains about seventy flourishing families of Urquhart descent, who all still speak Gaelic, and worship in that language in the churcheshttp://www3.ns.sympatico.ca/bryanfkeddy/novascotia.html

John McDonald was born at Glenurquhart and belonged to the Glencoe McDonalds. (* The History of Bridgeville, Pictou County, NS says that 'Old John McDonald of the 84th' was over 60 when he finally settled at Bridgeville, Pictou in 1784 - that would place his date of birth about 1720. * It also says that he was a veteran of Culloden)
At the time of the Glencoe Massacre, 1692, one of the McDonalds fled to Glenurquhart and settled there.
John McDonald was a grandson or great grandson of that man.
He was about eight years in the 84th Royal Highland Emigrant Regiment, and three of his sons fought with him in the American Revolutionary War on the Loyalists' side.
He was married twice. By his first wife he had Duncan, Alexander, Mary and Christy.
By his second wife, Margaret Grant, he had James, Ewen, Ann and Ellen.
Ann was married in Pictou to Thomas Fraser, Basin.
Ellen was married in Pictou to James Robertson.
Duncan, eldest son of John McDonald, was married in Halifax or Pictou to Catherine Fraser.
James, their third son, was born about 1759. He was a Corporal in the 84th regiment. He married in Halifax NS about 1782, Mary Forbes.
Youngest son, Hugh, is thought to have married Jane Grant in 1794. The marriage bond was posted in Halifax though Hugh lived in Pictou Couny (East Branch-East River, Upper Settlement) at that time
Christy married Duncan 'Speich' (Speech or possibly Speid) McDoanld, a son of John 'Og' McDonald. also of Glenurquhart (left the Glen in 1801).
