The land for St Mary's Catholic Cemetery in Norfolk, Virginia was purchased in 1854. Since that date, it has served as the resting place for Catholics from the Norfolk, Chesapeake and Virginia Beach areas of the state. This is an area of the United States that did not see a lot of immigration of Catholic from Ireland. As a result, the few Catholic parishes and cemeteries that they helped to create are important resources for genealogical research.
The About section of the cemeteries' website has a link to a database of interments that is hosted on the US Gen Web Archive. The database is considerable, with burials from the 1850s to the 21st century included. What makes this such a useful resource is that the information provided for each person was drawn from a number of different sources including original cemetery records, parish records, local death records, headstone inscriptions, obituaries and other records.
Names, dates of burial, dates of death, estimated years of birth, actual dates of birth and a link to an image of the headstone are provided for those in the database. Significantly, place of origin in Ireland is also included for some of the deceased.
For example, John M. O' Connor died on 16 October 1908. He was born about 1866 in Galway. Even though he is buried in Norfolk, Virginia, he died in Baltimore, Maryland. Patrick McCarrick was born in Ballina, County Mayo on 16 June 1821 and died 3 February 1888. He was a captain in the Confederate Navy.
Note: It is important to remember that the information in this database is a secondary source and was derived from primary source documentation. It is possible that mistakes occurred in the creation of this database so the primary source should be obtained wherever possible in your research.
