St. Patrick's Cemetery in Lowell, Massachusetts, was founded in 1832, in response to the need for a consecrated burial ground for the growing Catholic Irish community. The website of the cemetery has a genealogy section where you can search for information about burials that occurred from 1895 to 2011. All burials for those years are listed alphabetically in PDF documents. Provided information includes name, age at death, date interred, the location of the grave, and the name of the funeral director who arranged the burial, if know. This final piece of information could potentially lead to funeral home records.
More information about records before 1895 can be found in the comprehensive history of the cemetery. The website also has detailed maps of individual lots to help you locate a specific grave.
