Andrew,
sounds familiar - will check and get back to you either tomorrow night or Sunday night.
Carolyn,
thanks for your kind offer. Here is the conundrum:
According to the Crathie MI, Headstone 304 has the following inscription:-
"In loving memory of Mary Smith wife of James Mitchell d. Tynabaich Cottage, Crathie 8 March 1924 aged 72;
above James Mitchell d. there 4 November 1927 aged 78.
Alexander M. McNerney killed in action Rouen 29 July 1916 aged 26; his wife Anne Mitchell d. Tyhabaich 24 December 1952 aged 66. Their son Alexander T. McNerney accidentaly killed 20 August 1933 aged 20.
Base: 1 line text.
Plinth: Also Isabella Mitchell granddau of above James & Mary Mitchell d. 28 November 1970 aged 70"
So far so good and I can establish the stated relationships between all of these and have verified their dates of birth, marriage and death on SP. The last mentioned Isabella is a daughter of Maggie Mitchell, daughter of the James and Mary mentioned and her birth certificate confirms that she was illegitimate and had the full name of Isabella Edmonston McDonald Mitchell (I think there may be clues to her parentage in that name as none of those names are from her mother's line!). I found no marriage.
Information from a contact in New Zealand (who is not in touch now) also transcribes the same headstone and the information is identical until you come to Isabella. According to them this is what is written:-
Isobella Mitchell Crane - daughter of the above James and Mary Mitchell who died November 23rd 1950 aged 20 years. Blessed are the dead that die in the Lord"
you know, just as I type this I am beginning to see what the problem might have been!

She can't have been James and Mary's daughter, the time line is all wrong. But maybe the NZ connection read 'Crane' for 'Grand'; '23rd for 28th'; '1950' for '1970' and 'aged 20' for 'aged 70'. I'm more inclined to believe the MI - ANESFHS have been doing this for a long time and I'm sure they get it right.
Oh dear, I hope this isn't a wild goose chase but if you're still willing to go up there you might be able to see if there are any more recent inscriptions. The adjacent Headstones 303 and 302 are the same family. 298 - 301 inclusive also mention Mitchells but I have been unable to establish a link with them.
If you think it's not worth taking a look, that's fine too.
Enjoy your father-in-law's visit. Mine never visits, he says we live too far away which is a pity.
