This book will appeal to genealogists and historians alike. If you are on the lookout for an ancestor who might have worked in one or both of these trades, you will find over 1,000 indexed references indicating, in the case of traders, the date of the license, the licensee's name and address, and the amount paid; and in the case of ordinaries, the licensee's name, year licensed, turnpike mile post where the tavern was located, and its equivalent location in contemporary Baltimore County.
