Do you know who your great-great grandfather was. In looking at the timelines and names I am suspicious that my Patrick, born about 1852 was the son of a Michael and Johannah Ezekiel. It may be possible that your great-grandfather would have been my Patrick's nephew. Parents at that time often used the names of their parents for their own offspring. My Patrick had a Michael born in 1877 as well as a Johannah. I'm fishing and wildly speculating of course.
