[Q]: Richmond, Virginia (CNN) -- A historical society in Virginia, where slavery began in the American colonies in 1619, has discovered the identities of 3,200 slaves from unpublished private documents, providing new information for today's descendants in a first-of-its-kind online database, society officials say. Many of the slaves had been forgotten to the world until the Virginia Historical Society received a $100,000 grant to pore over some of its 8 million unpublished manuscripts -- letters, diaries, ledgers, books and farm documents from Virginians dating to the 1600s -- and began discovering the long-lost identities of the slaves, said society president and CEO Paul Levengood.The Virginia Historical Society finds 3,200 slaves named in private documentsThe unpublished documents are from Virginians' attics, basements and desk drawers"We sold all the negros 43 in number at astonishingly large prices," an 1858 letter saysOne user of the society's free database of slaves finds the owner of his great-great-great-grandfather

[Q]: Havana, Cuba (CNN) Hurricane Irma, which devastated much of the Caribbean in September, has claimed a new victim: Raul Castro's succession plans. On Thursday, Cuban officials said the island was still dealing with the aftermath of the killer storm and needed to postpone long-held plans for Castro, 86, to retire on February 24, 2018, when his second five-year term ends. It was to have been the first time that Cuba was ruled by a leader not named Castro since the 1959 revolution that swept Raul Castro's older brother Fidel Castro to power. The wrath of Irma, however, delayed the Communist-run island's single party elections process, which appoints the Cuban National Assembly that in turn selects Cuba's president.Cuba, dealing with Hurricane Irma aftermath, says Castro will retire in April instead of FebruaryCastro has indicated first Vice President Miguel-Diaz Canel has his blessing to be the next president 
 Question:"My second and last term will have concluded," _ told Cuban lawmakers on Thursday, "and Cuba will have a new president."
[A]: Raul Castro


[Q]: (CNN) -- To get through the long, tedious hours sitting in the fossil archives at the University of California-Berkeley, Jason Head would listen to the hypnotic sounds of The Doors.
