1: Skewball, Scewball, Scuball, Scu-ball
2: Miss- Portly, Sportly, Grizzel, Grissel
In a text in 'The Vocal Library', London, 1818, Skewball belongs to Squire Mervin, and Miss Sportly belongs to Sir Ralph Gore. Other versions sometimes give other owners. [Even at this early date the text is a bit corrupted. Text supplied on request]
Although the song is Irish, the only Irish traditional text I've seen is a relatively recently collected one in Hugh Shields' 'Old Dublin Songs', 1988. In the table of contents Sheilds puts the date at 1752, but never later mentions that or any other version of the song!
Where does "Griselda" come from?
