I have copies of nine trees byCR of the various Callow branches viz.
Ballaglass; Ballaskeig; Ballajora& Dreemskerry; Simon of the croft(Baldromma); Ballaterson; Claughbane; Ballacreggan; Ballagilley and Cardle Veg every branch but one is liberally supplied with Williams and although they make reference to Ballafayle there appears to be no continuity on this.
If you give me a better idea of what you are searching for I may be able to sort out information for you. At any rate I can try.
