Hi All, burning the midnight oil and a few bits of information and queries.
John, with ref to your post of 26/10/2012, you refer to David and William moving from Ayrshire to Argyll on the bid of the Duke of Argyll. What evidence do you have from the muck web site of the mention of your GGGrampa? do you have a hard copy I could get? I am sure I have B/M/D certs for some that show the farms they worked on mainland Argyll and on the Islands.
I have a photo of the grave stone for James Weir 1748-1810 (my 4xGGF) late of Auchengibbert, Old Cumnock. I agree their is a query on his age as it states he died aged 72 in 1810. making his birth 1738. It could be possible as his mother Agnes Hunter would have been about 17. can find no parish records for either B/M/D. I have copies of birth records for some of his children Marion 1793, Thomas 1790, David 1778, James 1776 my 3xGGF), Robert 1773, Janet 1770 also birth of his wife Jean Mitchel 1746-1825.
Regarding John Weir 1718-1788 My (My 5xGGF) his wife Agnes Hunter, I have a copy of his birth record from SP Parish records to a William Weir and Jean Good.
Regarding the marriage of David Weir to Margaret Hamilton and Thomas Weir to Mary Hamilton, according to my research Margaret and Mary were not sister.
It is worth visiting
https://cumnockconnections.tribalpages.com which has an extensive database for families living in the Cumnock area.
Note When James Weir jnr married Agnes McCrone the parish records show the following:-
Marriage 29 Nov 1800 • Old Cumnock, Ayr, Scotland
James Weir junior, Auchingibbert and Agnes McCrone, Borland.
Agnes McCrone (1774–1858)
So James Weir snr was farming Auchengibbert in 1800 at the time of his sons marriage. this relates to the inscription on the gravestone and it is the right James Weir senior although his age appears to be wrong. Interesting that your horse tax record shows James Weir snr living at Auchengibbert in 1798.
I have the monumental inscriptions for Old Cumnock graveyard and can't find the stone you refer to in your item 4.
Must stop now too tired to be continued
Best regards
Graeme
