Background
Hastings Hornell Hart was born on December 14, 1851 in Brookfield, Ohio, United States. He was the second son and third child in a family of five children. His father, Major Albert G. Hart, was a veteran of the Civil War and a practising physician, a descendant of Stephen Hart, who arrived from England in 1632, living for a few years at what is now Cambridge, Massachussets, where he served as deacon of Reverend Thomas Hooker's church. He went with Hooker's company to Connecticut in 1636. After a brief sojourn at Hartford he settled at Farmington which he later represented at various times in the legislative assembly of the colony. Hart's mother was Mary Crosby Hornell, whose great-great-grandfather was a Swedish clergyman, Nicholas Hornell, who emigrated to America in 1762.
