Looking for any information

I have just learned that my gg-grandfather, HUGH O'HARE, was from Kilpatrick, County Down. He was likely born around 1795-1805. He married HANNAH BURNS, born about 1805, in Ireland. They were ROMAN CATHOLIC.

They emigrated to Canada, probably around 1828. One daughter, born in Ireland, died on the voyage. The next child, also female, died in infancy and is apparently buried somewhere around Tyendinaga, County Hastings, Ontario. I can account for the next five children. The last child, a female, burned to death playing around a fire.

Hugh (1795-1805) died prior to the 1851 census as Hannah was listed asa widow. My g-grandfather Hugh (1841-1927) left Canada and settled in the Titusville, Pennsylvania area in the USA.

I would love to learn anything about any of the O'Hares from the Kilpatrick area and their descendants. My dad used to say that my brother is the 7th Hugh which would mean that that the father and grandfather of Hugh (1795 - 1805) were likely also named Hugh.

Thank you in advance for any help you can give me. Sincerely, Sarah O'Hare Amy
