Shavouah Tov,If you one of your ancestors stayed in Gibraltar between 1700 and 1914, you may be able to find him in the city archives by clicking on the following link: http://www.nationalarchives.gi/gna/Inhabitants.aspx. The censuses are posted per year (click on " inhabitants " then on " Civil Records "). All the city's censuses are accessible between 1704 and 1914. There is no search engine but individuals are classified by religion. For Most of them age (thus deducting the date of birth), the number of years of presence in Gibraltar, sometimes the profession and address are indicated. To find the composition of the family, refer to the source documents ("Original Records"), also available on the website.Enjoy!
