Colonial records of French and Spanish slave ships and sales, and plantation records in all the former colonies, often have much more information about slaves, from which researchers are reconstructing slave family histories. Genealogists have begun to find plantation records, court records, land deeds and other sources to trace African-American families and individuals before 1870. As slaves were generally forbidden to learn to read and write, black families passed along oral histories, which have had great persistence. Similarly, Native Americans did not generally learn to read and write English, although some did in the nineteenth century. Until 1930, census enumerators used the terms free people of color and mulatto to classify people of apparent mixed race. When those terms were dropped, as a result of the lobbying by the Southern Congressional bloc, the Census Bureau used only the binary classifications of black or white, as was typical in segregated southern states.

On 27 August 2007, Royal Dutch Shell and Reitan Group, the owner of the 7-Eleven brand in Scandinavia, announced an agreement to re-brand some 269 service stations across Norway, Sweden, Finland and Denmark, subject to obtaining regulatory approvals under the different competition laws in each country. On April 2010 Shell announced that the corporation is in process of trying to find a potential buyer for all of its operations in Finland and is doing similar market research concerning Swedish operations. On October 2010 Shell's gas stations and the heavy vehicle fuel supply networks in Finland and Sweden, along with a refinery located in Gothenburg, Sweden were sold to St1, a Finnish energy company, more precisely to its major shareholding parent company Keele Oy. Shell branded gas stations will be rebranded within maximum of five years from the acquisition and the number of gas stations is likely to be reduced. Until then the stations will operate under Shell brand licence.

As the century wore on, the factions slowly began to adopt more coherent political tendencies as the interests of their power bases began to diverge. The Whig party's initial base of support from the great aristocratic families, widened to include the emerging industrial interests and wealthy merchants. As well as championing constitutional monarchy with strict limits on the monarch's power, the Whigs adamantly opposed a Catholic king as a threat to liberty, and believed in extending toleration to nonconformist Protestants, or dissenters. A major influence on the Whigs were the liberal political ideas of John Locke, and the concepts of universal rights employed by Locke and Algernon Sidney.

Ah, so..
