Anne - I think every Corcoran family named a son "Patrick", as there are so many of them it is difficult to sort them out. With us, it was easy. We knew Our Corcoran-Haster were married in Syracuse, and St. Mary's is doing a lot of work in their archives and transcribing all of their marriage records. They gave us the date of the marriage, 7 June 1855, and the names of the witnesses. We hope those clues will lead to something. Nothing yet. I don't know if all of the Corcorans are related. If you know which Parish your Patrick was born, you should be able to find his parents. In our case, we have the exact date of birth, but only the name County Mayo - the most populous county in Ireland. We need to know the name of the Parish. I am not familiar with Orville or Dewitt. If your Patrick was married in Syracuse, St. Mary's, it will be easy for you to get the info. Do you know how your Patrick got to NY? We have not found our Patrick on any passenger lists for NY or anyplace in US, although there are many by the name of Patrick Corcoran. We will search for an entry from Canada to NY. I hope that we can trade info as we get it. Regards, Margaret
