This is a very useful concise history of Ireland for anyone wishing to get an overview of the subject, and has been written quite objectively.
A History of Ireland and Her People by Eleanor Hull
A more in-depth history, well-written and with good objectivity. It covers the History of Ireland from the earliest times until the early part of the 20th century.
The Story of Ireland by A. M. Sullivan, circa 1900.
Sullivan leaves you in doubt to his religious persuasion and political beliefs in this history. The book was published as part of the Atlas and Cyclopedia of Ireland, 1900.
An Illustrated History of Ireland by Margaret Anne Cusack (or Sister Mary Frances, Nun of Kenmare), 1868
Cusack converted to Catholicism and became a nun before eventually reverting back to Protestantism. This history was written whilst she was in the convent and with the zeal of a convert. As with most 19th century histories of Ireland the objectivity of this book can be questioned, but it nevertheless contains plenty interesting information and useful footnotes.
