I hope I haven't given you too much bother.
If my research is correct, I have three brothers, John Grayson born 1786 in Co Tyrone and moved to Boconnell, His children emigrated to Australia.
Thomas born 1794 in Boconnell. He remained in Boconnell, four of his sons emigrated to New York, but my Grandfather Thomas, remained in Boconnell.
Francis Born 1798 in Boconnell his family also emigrated to Australia.
Does the book mention the first Grayson's in either Co Tyrone or Boconnell Lurgan.
I do not know who the father of John, Thomas or Francis was.
Thank you again for your assistance with my research into the Graysons.
