Great Great grandfather was James Gilmore,born abt 1803,died around 1846 of typhus. Family was Presbyterian. Married Martha Matildah Smith, born 1807- nine children- James,Ann, John, Eliza, William, Catherine, Isabelle, Frances, Thomas.They resided near Oghill at one time, then Omagh. Oldest son born 1828, youngest 1846. All children and mother left for America 1847-1848. Any information appreciated. Know nothing about parents siblings, their parents.
There’s no Gilmores listed in the tithe applotment records for Oghill in 1826 indicating either that the family didn’t live there at that time or that if they did, they did not have any titheable land.

The two nearest Presbyterian churches to Oghill would appear to be Albany and Brigh. Albany’s baptism records start in 1841 and Brigh in 1837. In Omagh there are several Presbyterian churches: 1st Ballynahatty bapts from 1843; 2nd Ballynahatty bapts from 1867; Gillygooley bapts from 1848; 1st Omagh 1856 2nd Omagh bapts from 1821.
So none has records early enough to trace the parents baptisms (or that of any siblings) but you might find some of the later children if the family happened to attend any of those churches with records for the 1840s and earlier. I don’t think these records are on-line anywhere but there are copies in PRONI (the public record office) in Belfast. A personal visit is generally required to access them.
