Hi Kathy
I've checked the Annat entries for you - there are four stones that mention MacLeans, but not a John MacLean and Catherine Fraser.
The stones are as follows:
"Roderick McBeath died Fassag 1842 aged 47, wife Ann McLean died 1877 aged 84, daughter Ann died Feb 1914 aged 80 years
Flora Macdonald, husband Donald Maclean, died Callakille 12 June 1890 aged 84 years, daughter Annabella died Shieldaig 1852 aged 14 years, Norman Macdonald, merchant, died Ardmore 2 May 1878 aged 72 years.
Erected by Roderick and Grace Maclean, father Kenneth Maclean, innkeeper died April 1845 aged 56 years.
John Murdoch, born New Cumnock 1774, tenant Corry, Torridon for 13 years, died 1845, wife Barbara Mitchell born 1778 died 1852, son William born 1815 died 1896 (wife Mary Maclean born 1824, died 1874)."
The book does also have Kishorn, Lochcarron, Locharron Old and Applecross (as well as quite a few other burial grounds, but these are a bit further away from Annat). Just let me know if there are any others you would like me to look up for you.
By the way, my Gairloch MacKenzies are from the Aultbea/Laide/Mellon Udrigle area of the parish, just about 5 miles north of Poolewe - any connection do you think?
Look forward to hearing from you
Lynn
