The distribution of U.S. surnames reflects the history of immigration into the country. Many immigrants from non-English-speaking countries Anglicized their names. Some examples are the popular Swedish name Johansson, which was frequently changed to Johnson, and the German Müller, which became Miller. Some very common Swedish names were so similar that only a minor change of spelling was necessary, such as Andersson and Jonsson, which is why these names are much more common in the U.S. than in the United Kingdom. British surnames such as Williams, Jackson, Robinson, Harris, Davis, Brown and Jones are also common among people of non-British descent, such as African Americans due to slavery. Garcia and Martinez represent the rapid growth of several Hispanic communities in the United States.
