Betty, I forgot to say, he and Catherine did not have any children as she was well into her 40's when she married him, however I do have in my notes that he could have been married to a Philadelphia Smith. Where I got that from is anyone's guess and because he was not my relation, I didn't go any further. Perhaps you are from that line?
I have just seen this on the Internet. My gggg grandmother was the Catherine O"Dell in question. She had been married twice before. I don't know much about him at all, although I have seen his name mentioned in various lists pertaining to Cork. I believe they lived at "Woodpark" which from memory was located down near the coast.
I hope she and James had a happy life together, She had come from a privileged background and she and my gggg grandfather lived in style at "Castle Kevin" near Mallow, indeed that is where my gg grandfather was born.
I am writing this from Australia. I have been doing the family history now for 35 years and these ancestors are like my "bosom friends". I would love to know anything about James Carmichael and would be thrilled if you could let me know.
I´m also involved with the Carmichaels` who were married into the Tarrant family (tarrant.gen at gmx.de).
The Woodpark property you mentioned was according to my records belonged originally to the Wrixon family in the 18th Century. In 1814 T. Callaghan lived there for some time up to the mid-19th Century when James Carmichael made it to his residence. He rented it from the Purcell Estate at a valuation of 11 pounds 10 shillings Sterling at the time of Griffiths Valuation. The Carmichael´s later bought the property outright from the Purcell Estate. I believe it is still occupied to this day as a residence. I hope I have been of some help and would be delighted to hear more about your Carmichael research. My Mail address is above should you wish to contact me regarding Carmichaels.
