My 2nd great-grandfather was James Hodgen, born May 11, 1802 in Portadown. I believe he had a sister Deborah, and he and his wife, Jain Jones, emigrated to Ontario in Apr 1826. Their 3rd child was named Deborah, born 10 Jun 1830, who married a John Gibson on 19 Dec 1849 in Talbot County, Ontario. John Gibson was born 10 May 1829 in Ireland. I have no information on ancestors of James and Jain in Northern Ireland but continue to look and hope. Although much earlier times than you have quoted, perhaps there is some linkage with your family.
