Looking for Given Name and Birth Place IN Ireland for a Mr Hannah

In starting my genealogy research, I came across a site on which a distant relative of mine, had already done much of the work. He has traced our family back to a Mr. Hannah who was born in Ireland about 1790. He had three children. A girl, Esther Hannah, born about 1809, in Monaghan, Ireland; a boy, Thomas Hannah, born about 1810; and another girl, Susan Hannah, also born about 1810. Thomas and Susan were both born in Ireland, as well. It is unknown as to whether the last two children were twins.

The family immigrated to Canada, and took up residency in the Quebec, Montreal area. While I have no info on the death of Mr. Hannah, his daughter Esther Hannah died July 16, 1886, in Quebec, Montreal; while her brother Thomas moved to the United States, and died October 1, 1899 in Belvidere, Boone, County, Illinois. No record of Susan's death has been found.

What I hope to find, is Mr. Hannah's given name, as well as the exact place of birth for his children, in Monaghan (Parish), Ireland, and possibly any records of marriage or residency in Ireland. If you happen to have any info on these persons, or know where I might could find such info, please let me know.

Thank you for taking the time to read this, and for any help you may be able to give.
