Hi Blanched
All the Downie memorials are more recent than the ones you asked for. But I'll give them to you anyway because they might be of interest.
St Quivox 1st
1) Mathew Downie d 9 june 1920 aged 60,
wife helen Stewart d 16 feb 1947 age 85
their infant children - Thomas, Christina, Mathew. That is so sad.
2) erected by James Bush for his wife Janet Black died 10 july 1881 aged 63 and her son Andrew Downie d 20 march 1883 aged 35
3) in memory of Jane Downie widow of William Downie b sep 1758 d 4 sept 1844 erected by her son Peter Ballantyne of Newark State of New jersey usa.
4) Elizabeth Downie wife of John mcCulloch d 29 may 1922 aged 61. (She must have been the 2nd wife because his 1st wife and hoards of a family are there too.)
5) Robert Bell Kirkland d 23 sept 1938 aged 81, husband of Agnes Campbell Downie d 16 feb 1942 aged 79. also their dau Agnes d 17 feb 1943 age 55.
In the Newton green cemetery in Ayr itself three are 2 Downie's
1) John Boyd native of Troon d Glasgow 1 oct 1876 aged 55
wife mary Downie d Glasgow 17 april 1881 aged 58
(it has the same scripture verse as one of the above)
2) James MArr d 22 sept 1832 aged 62,
his wife Margaret Downie d 4 dec 1863 aged 86,
their children - quite a lot - if you want them let me know.
And there is one memorial in Wallacetown cemetery
1) Erected by Elizabeth pearson in memory of her father James pearson d 4 july 1868 aged 66,
also her mother Annie Downie d 24 may 1886
who are Interred in Stair cemetery
and then various other relatives - again, let me know if you want them.
I hope there is something there for you to go on. I gave you the others because they are older and you might have some connections for them.
Here's hoping!
good hunting
