It is believed that Ninian Boog migrated to Virginia from Scotland about 1749 and died before December 1754. Ninian Boog’s store was in King and Queen County, Virginia. Merchants typically kept a daybook in which would be entered each transaction as it occurred in chronological order. The data would then be transferred to a ledger and all the accounts of one individual would be entered under that person’s name. Ledgers were usually neater than daybooks and usually also contained an index in the front or back. Swem Library holds Ledger A as well as a daybook. The Library of Virginia holds Ledger C. The Swem volumes have been microfilmed.
