I sure hope you still visit this Website, mikymc, in 2016!
My g-g-g-grandfather was Irishman Roger McCormick, who married Mary Darragh.
His son, my g-g-grandfather John McCormick (born circa 1840), relocated to Port Glasgow, Scotland. One of his children was Mary McCormick, my g-g-grandmother, born May 30, 1858.
I have more concurrent and later information.
Can we share?
