Question: Which tribe was Chief Blackfish the Chief of? Passage:Little documentary evidence of Black Hoof's life appears in the historical record before 1795. As a child he may have been a member of a waundering band of some 400 Shawnees led by Peter Chartier between 1745 and 1748, who founded the community in Kentucky called Eskippakithiki and later moved to Sylacauga, Alabama, eventually settling in Old Shawneetown, Illinois. He probably took part in the Battle of Point Pleasant during Lord Dunmore's War against the Virginia militia in 1774. During the American Revolutionary War, he may have taken part in the siege of Boonesborough in 1778, which was led by Chief Blackfish, as well as the subsequent defense of the Shawnee village of Chillicothe in 1779. In the Northwest Indian War, Black Hoof was defeated by "Mad" Anthony Wayne and, following the collapse of the Indian confederation, surrendered in 1795.

Question: How many people lived in Scone the year Wilshire first began serving as a clerk there? Passage:He was born in Sydney to James Robert Wilshire and Elizabeth Thompson, a member of a prominent and well-connected colonial family. He was educated at Peter Steel's School in Pitt Street and Henry Brown's City Grammar School before studying at the University of Sydney. He was a clerk and land agent at Scone from 1862. In 1883 he returned to Sydney, being now wealthy enough to retire. He was an alderman and mayor of Burwood, and was involved with a number of societies, notably those connected with sanitary reform. In 1889 he was elected to the New South Wales Legislative Assembly as one of the four Free Trade members for Canterbury, but he did not contest the 1891 election. Wilshire moved from Burwood to Neutral Bay, New South Wales in around 1894 (as did his half-brother Henry Austin Wilshire), and lived there until his death in 1909, leaving to his widow a substantial portfolio of local properties. He had no children.
