Here's an announcement I received of an interesting project sponsored by the Ulster Historical Foundation. If you had Scots-Irish ancestors from Ulster who emigrated around this time, you might want to contact this group.
"Research projects are central to the Foundation's mission of seeking to tell the story of the people of Ulster. Forthcoming projects will include an Irish in the Plantation Map, similar to those already completed on the English and Scots in the Plantation and Presbyterian Exiles of 1798. With regard to the latter project, we would be grateful for your assistance. The Foundation has been commissioned to carry out research into Ulster Presbyterians who sought refuge in the United States around the time of the 1798 Rebellion. Many Presbyterians in the north of Ireland, (in addition to other Protestant dissenters and Catholics) supported the United Irishmen, resulting in numbers of them having to leave the island. Our aim is to find out more about these individuals and their experiences in the United States.
We have assembled a team of academics and researchers on both sides of the Atlantic to investigate this further. If you have an ancestor who was involved in the United Irishmen and who had to leave Ireland as a consequence, we would be interested in hearing from you. Any information you share with us will be treated confidentially and will not be made available in the public domain without your permission. Please email: firstname.lastname@example.org including 'Presbyterian Exiles of 1798' in the subject box."
