There definitely seems to have been a close connection between James Bryson of Ballyvoy and John Bryson of Ballywee. They possibly exchanged or shared land in Lisnalark? Witnesses to each other’s deeds.

[This is probably the western two thirds of Duncansland.]
I don’t know much about Thomas Ferguson of Doagh other than I think he died in 1832 and his eldest son was possibly James Ferguson of Ballybracken. His second son was called Thomas and married Sarah Fulton of Standingstone in 1833.
