Alan O’Day 
A Survey of the Irish in England (1872) [PDF ebook] 

A Survey Of Irish History collates sixteen letters regarding immigrant communities by High Heinrick, which were originally published in the Irish Catholic Nationalist newspaper
Nation in 1872. Alan O“Day provides an excellent introduction to the letters, and by bringing them together in one volume, offers an essential contribution to the history of Irish immigrants in 19th century England. These materials illuminate the diversity of Irish experience, in terms of financial situation, political and religious organisation, and social status.
