Notes
[1] Beatty: This pedigree is here incidentally given among the families descended from Heremon; but while Beatty and Battie are of Irish origin, the lineage of the family is not yet ascertained. The names are derived from the Irish biadhtach [bee-a-ta], "a public victualler"—For information in relation to the ancient biatachs in Ireland, see Paper "Monasteries," in the Appendix.
