Family story tells of Andrew Lynd being one of seven sons whose parents died when the children were young. It is most likely they came from Gortin in Aghadowey parish originally. Andrew married Margaret Perry of Scalty and settled at Knockaduff.
Their daughter, Margaret Lynd of Knockaduff went to Ontario, Canada with her brothers and eventually they all moved to Michigan, U.S. She married a Lynd born in New York and had children.
Thomas Lynd (grandson of Andrew & Margaret of Knockaduff, Aghadowey) moved across the Bann to Ballybrakes, Antrim and then after a few years the family went to live in Moosomin, Sask.

There were also Lynds in Cookstown area but suspect they are not connected.
