Does anyone have relatives related to Cornelius Harrington (we think he was born May 1836 in Cork, Ireland) and/or Mary Conroy Harrington (also her maiden name, born around 1842 in Cork, Ireland)? The earliest reference to them that we can find is their marriage registration in Houghton, MI on September 22, 1863. Witnesses were Daniel Shai and Mary Sullivan. Married by James Sweeney, Catholic missionary. Thank you. Betsy Harrington
