There is much valuable material in the Register (Frankfort, 1903 seq.) of the Kentucky State Historical Society, and especially in the publications of the Filson Club of Louisville.
Durrett's John Filson, the first Historian of Kentucky (1884); Thomas Speed, The Wilderness Road (1886); W.
8 of the Filson Club Publications; J.
Plunkett, Ireland in the New Century (London, 1905); Filson Young, Ireland at the Cross-Roads (London, 1904); Thom's Almanac, published annually in Dublin, gives a very useful summary of statistics and other information.
