Consider it done, and very many thanks for your kindness in responding to my posting so quickly. For the sake of other researchers of Fife families, I am more than happy to work with you on researching certain Fife families.
You tell us, LaVerne, that your interest is in Peter Grieve, who married Isabell Harvey. Peter, as you correctly stated, was the brother of Andrew Grieve who married Jane (Jean) Dalrymple.
Although you may have this, I include it for the benefit of all other researchers:
Jean Dalrymple, the widow of Andrew Grieve, was aged 41 when she was interred in Peter Grieve's grave at Coaltown of Balgonie in Fife on 20th December, 1831. That means that her birthdate would have been around 1790. Peter Grieve had been interred on 11th July, 1823 feet-to-head of James Grieve at Coaltown of Balgonie, interred 23rd January, 1831.
I will be delighted if the above is of some use to you, LaVerne, as well other researchers.
