As a youngster, Christopher Koch was intrinsically aware of his mixed and tremulous heritage. When Margaret O'Meara, his Tipperary born, rebellious great-great-grandmother, boarded the Tasmania to travel as a convict to the southern hemisphere, there began a new dimension within Christopher's family tree; a secretive past that his mother refused to discuss. Many years later it was in Tasmania that the young Christopher grew up, and here that he began his lifelong quest to better understand his ancestral roots, a quest which rears its head in his travels around Ireland in the 1990's.
