Many Irish emigrating to America came via Canada and the St Lawrence River. Leaving the boat in Quebec, many found their way down Lake Champlain and the Hudson River to the Troy/Albany area of New York state. The parish of St John's Church in Albany became overwhelmingly Irish during the famine years. Recently, the old interment books of the St John's cemetery were discovered, and the Troy Irish Genealogical Society (TIGS) has scanned and transcribed the deteriorating records. According to the TIGS website: The 12,731 entries in the recovered book start with interments in August 1841 and go through September of 1887... The one item in this interment book that will delight genealogy researches is the identification of the County in Ireland where many of the individuals came from. Generally in researching old records for Irish immigrants you only see the words Ireland and nothing further.

A breakdown of the Irish immigrants show the following:

Antrim 10	Kerry 76	Queens 114
Armagh 35	Kildare 38	Roscommon 159
Carlow 80	Kilkenny 195	Sligo 47
Cavan 307	Kings 114	Tipperary 458

 The TIGS summary about the St John's cemetery project is fascinating to read. But even more special, the database of 12,731 interments (1841-1887) is searchable online.
