Hello Whiteout:
Thanks for all your info. I've got to take time to understand it.
At this point I've got to post the record I mentioned: it's the baptismal record of James and Jessie Burke's first child. Not only is his first name Francis, he also has "William" in his name. Lady Charlemont's husband was named Francis William.
Francis Xavier William Burke, born Dec. 2, 1851 (less than 8 months after James and Jessie's April 20 1850 wedding).
So you can all understand my incredible excitement at this discovery compared to my speculations of connection to Lady Charlemont: the passing of "Francis" across three generations in this context just screams confirmation. Then, the inclusion of "William" absolutely dumbfounded me. It was as if Lady Anne Caulfield was slapping me upside the head, telling me to put all doubts aside.
-------------
James Caulfield, 1st Lord of Charlemont has a son:
William Francis Caulfield, 2nd Lord of Charlemont.
Then John Burke and his wife have a son James Francis Burke, who brings to America the artifacts of "Lady Anne of Clontarf"
Then James Francis Burke names his first son Francis Xavier William.

I am very interested to hear everyone's thoughts.
Joe
