Hello! Hope you don't mind me throwing my hat into the ring so to speak! I am currently doing a family tree for someone who has a Sarah Greenwood as his forebear. This Sarah Greenwood was born in 1874 in Muirkirk, the daughter of Joseph Greenwood and Isabella Barr - her sister was Isabella Barr Greenwood, who was her bridesmaid at her wedding to Alexander Reid in 1893. Sarah and Isabella were sisters of Thomas, Joseph, William, Mary and David Barr Greenwood. Both Joseph Greenwood and Isabella Barr were born in Ireland. Don't have any more information I'm afraid at this point in time, but if I find out more, will post it.
