Hallo, I placed the Curiousfox ad and have been corresponding with Dollylee. Finally, I have retrieved my username to join in the Paton chat!
Margaret Cunningham was the second wife of a John Paton born in 1701, the grandson of the famous Captain John Paton 1614-1681. I am fairly sure the Captain is an ancestor of grieving heiress (or not as the case may be) Janet Paton.
I think that whoever, on Ancestry.com, has given Janet Paton's father a second wife simply got their John Patons muddled and that Janet Paton's mother Margaret Dickie was still alive in 1841 living in Gauze Street, Paisley with the Beatons.
Worth looking at
http://hometown.aol.com/rosecote/myhomepage/heritage.html showing that the Ayrshire Patons were a breed unto themselves and separate from the Paisley Patons (mine) even though some may later have moved up to live in Paisley alongside the indigenous Paisley Patons, who were, by the way, all drapers to a man. And the Alloa Patons were another entirely separate branch again.
Gauze Street, Paisley was not a great address. I don't know why any Paton from Alloa with a connection to factory wealth would choose to live in Gauze Street, Paisley.
Has anybody set out in a list the Christian names of Janet Paton and John Beaton's children. These can be a great pointer in the right direction.
By the way, I have identified John Beaton's first wife as Florie Paton, daughter of James Paton b 1772 and Jean Paterson, who married 29 November 1806 and had Florie 24 October 1807. The name of Florie and John Paton's daughter Jean Paterson Beaton clinches it
