Just received some additional information. Mary Farrelly was the daughter of Patrick Farrelly and Elizabeth Kellett. She was born in Closenabraddan, Kingscourt, Cavan. I do have a date of birth but would estimate it is between 1835 and 1845. I think she probably died between 1873 and 1877 based on birth of last child and birth of first child of John Carolan's subsequent marriage.
