I was excited to have you find any direct relation to Henry in Jean Ann living in Huntly of all places - very Gordon territory. Very near the castle.
Actually she was in the parish of Culsalmond, so she wasn't all that near Huntly Castle.
Did Jean born 1805 (Anne’s sister 1808) daughter of John Gordon marry a McKenzie.
There is a death of Jane Gordon or Grant, mother's surname Collie, aged 89, in 1894 in the parish of Abernethy and Kincardine, Inverness-shire. This is the next parish to CIA.
I have found that William 1791 had parents Wm 1751 and Marg nee Sutherland and can go back to 4th Earl of Seaforth and beyond. (Family Search). I would now like to claim them.
If you got that from some online tree or other,
do not trust or believe it. Check every step of it for evidence and proof, and until you have such evidence don't 'claim' them.
I have come this far so now want John Gordons parents. Married at Knockando to Christina Collie, and parents of Ann.
This may not be possible. They were married in 1797 and their family were born 1798-1811, so John and Christian/Christina were probably born before 1780. Unfortunately the early records of Knockando were destroyed when the session clerk's house went on fire in 1783. The volume starting in 1767 was saved, but the minister who wrote the New Statistical Account commented that the register was very incomplete because parents were neglecting to have their children's baptisms recorded.
There is a possible candidate for Christian Collie; baptised in Knockando 15 November 1770, parents James Collie and Agnes McRobbie. However there are other candidates in other parishes, and it's always possible that she was one of those whose parents neglected to have her baptism recorded.
There are deaths of William Gordon, 88, in 1899 and Elspet Gordon, aged 85, in 1900, mother's maiden surname Collie, both in Inveravon. The 1881 census lists at Drumgrain, Inveravon William Gordon, 69 and his sister Elspet, 64, both born in Cromdale. Inveravon is on the other bank of the Spey opposite Knockando and CIA.
In 1851 William was already at Drumgrain with wife Margaret Hay and children Christina, John and William.
In 1851 Alexander Gordon, tailor, 48, born Knockando and his sister Elspet, 34, are at Kilmaichlie in Inveravon.
Drum(a)grain is a mile or so south of Balindalloch Castle
