I am looking for information on Mary Ann Pluck, she is my 4th g-grandmother. I know she was born sometime around 1827 in, I believe, Ohio. She married Edward McGourn in Ohio sometime around 1846 and had 4children, one of whom was Lovina McGourn who married Jeremiah Mackley (my 3rd g-grandparents). She died around 1900 in Mansfield, Ohio.
