Sue,
Here are the Ballaskeig links to Kerruish,
1 William 1679-1732 1st.wife Kathleen Kerruish d.1715 E
2 John b.1684 m. Catherine Kerruish this John is a younger brother of the above William
3 Another Brother Edward 1683-1761 m. Ann Kneale had daughter Catherine d.1756 the mother of Edward Kerruish.
Most of the other Callow trees also have one or more links to Kerruish although one on the Claughbane tree has a question mark.
Hope this is some use, if I have your e-mail I can send the other links without clogging the board.
Rick
