There are two organizations of interest if you live in the Buffalo region of New York and are looking to start tracing your Irish ancestry. Firstly, there is the organization that is indispensible to every genealogist, the local library system, in this case the Buffalo and Erie County public library. They have produced a helpful online publication, Irish Genealogy: Selected Sources in the Grosvenor Room. The Grosvenor Room houses the special collections.
Among the usual listing of books and resources, one in particular caught my eye. The Buffalo Irish Genealogical Society, the second relevant organization, carried out an indexing project of Irish burials in Holy Cross Cemetery, Lackawanna, NY. This index was published in the Buffalo Irish Times, a paper aimed at the Irish community in the area. The records cover 1872 to 1964, and are available on microfilm in the Grosvenor Room, call number WNYGS ML229.
