This John McDonald is my gggg grandfather. I suspect that he is from the Ardnabie line but I'm wondering if anyone has any further information to confirm the line and when he emigrated.

Lancaster 6 Lot 33 (land records have them there as early as 1787):
John McDonell (1764 - 1843)
wife - Janet McDonell (1764 - 1864)

Nov 17 1843 death: John McDonell, age 74, son of Ranald McDonell & Janet Fraser. (St-Raphs)

July 9 1864 death: Janet McDonell, age 101, in Lanc 6/33, widow of John McDonell son of Ranald of Ranald of Alex OG of Angus of John of Donald "A Lagain". (Fr John's Diary)

The chart on page 247 of Fr John's Diary shows this line with another Ranald "Ardnabi" also connecting into it. Up until the Ranalds it coincides with the published info on the Ardnabie's I've been able to find.

There are a number of John's (Lanc 6/33) descendants' obits which confirm the Ranald of Ranald entry.

I can't seem to find any other documentation that confirms that Alex OG had a son named Ranald. Duncan Darby's research doesn't follow this part of the line.

I would also like to try to confirm if John & Janet came over in 1785 or 1786 or if they were UELs. Although I have compiled a list of their children, I have no idea who his siblings were and whether they and/or their father Ranald emigrated with them.

Any help would be most appreciated.
Thanks,
Lara
