Hi Gadget,
Not too sure about my Irish history, I have been to Dublin, went to Kilmainham Gaol, what a bleak place this is(was). It held some of the people from the 1916 rebellion, and was a very cruel place. I thought the break up was then but I stand to be corrected.
Isabella Jane disappears in the 1861 census too, I pick her up as a 22yo wife of James B Peacock in 1871.
