Hi Brian,
I will try and answer some of your questions -
S.R stands for Southern Reporter (Cork newspaper) first published twice weekly and later published thrice weekly.
I checked the entries on Rosemary Ffolliots newspaper extracts for "Blair" and there is a little extra information that confirms Margaret was the christian name of "Miss Blair" .
CMC (Cork Mercantile Chronicle) W (Wednesday) "last week Capt. George Audley to Miss Blair of Bantry.(MLB Margaret Blair. Married at Christchurch 11 Jne.) MLB = Marriage licence bonds.
I don't know if the Margaret Audley who married Thomas Blair Patteson on 23rd July 1825 was Capt. George Audley's widow. You could be correct in thinking that.
South Mall was a very upmarket area of Cork City in the 1800's. See photo -

www.corkpastandpresent.ie Christchurch is on the South Main Street in Cork City - It is called Holy Trinity church but known as Christchurch. You asked me how I knew they married in Christchurch it says so in the newspaper extract.
The Church of Ireland site
www.ireland.anglican.org did have some records on their site but not many. They are based in Dublin and hold most of the BMD records for the country however they don't do look ups. You would need to visit their library.
Registers held at the Church of Ireland Dublin -
https://www.ireland.anglican.org/about/rcb-library/list-of-parish-registersI do have a book of Christchurch records for the years 1643-1669 which isn't any help to you.
Here is info on Cork Parish Registers ( Church of Ireland)

http://landedestates.nuigalway.ie:8080/LandedEstates/jsp/estate-show.jsp?id=2490I have tried to find "Capinaweel" I think it might be a mis spelling and it seems like an English spelling for an Irish townland or area. I tried the site
www.loganim.ie and didn't come up with anything sorry.
I found some Blair entries that might interest you . I will send them on in a few minutes.
Mary.
