| Dedicated to Descendants of Lawrence O'Brien (1826-1904) and Mary Lynch (1835-1921) |
| This web site was created to assist the Lafayette County, Wisconsin descendants of Lawrence and Mary O'Brien find their ancestors. Lawrence O'Brien and his wife Mary Lynch are registered as "Pioneers of Wisconsin" with the Wisconsin State Genealogical Society. This site has significant amounts of information on the descendants of Michael O'Brien (1865-1938) and his wife Ellen (Nellie) Carolina McDermott (1872-1957). Michael and Ellen's oldest living descendents are Loretta Bolzenthal, Gerald O'Brien and Lorraine Gille. |
| It would be great to have hundreds of Lawrence and Mary O'Brien's descendents sign the guest book and add stories, photographs and other relevant information to the site. Slainte! Sandi Callaghan (Great-great-granddaughter of Lawrence and Mary O'Brien) |
