Yes, I do have some more information. Working backwards. My gr gr grandfather, William Griffin born 1841 in Co Cork, Ireland emigrated to the US in 1858. From his marriage record in New York City, I found that his parents were Jeremiah Griffin and Catherine Courtenay. I found Jeremiah Griffin and Catherine Courtenay's marriage in 1840 in Imogeela RC Parish in the Roots Ireland indexes. I also found baptism records for 4 children born between 1841 and 1849. From the records on the National Library of Ireland website I was able to view the actual records. From the NLI records I found that the family was living in Ballymacoola when the first three children, William, Honora and Edmond were baptized. In 1849 the family was living in the Midleton workhouse when son Jeremiah was baptized.
So now I wonder if there are any records from the workhouse. Thank you in advance for any guidance you can offer.
