I have an Esther Kelly born in German March 1766 of William Kelly and Jane Morrison. She married Charles Kewley 25 Jan 1794. I have no further information on William Kelley, who may be the same as your William Kelley. Charles Kewley's mother was an Ann Cretney who married John Kewley and died 4 July 1803. They lived in Greeba. This Ann Cretney's mother was also Esther Kelly, daughter of Robert Kelley and Bahee Looney. John Kewley's great grandmother was an Alice Kelly married to a Henry Crellin. I believe Crellins were also in Greeba.
