Surname maps are maps which display and indicate the highest concentration of residents with a particular surname, or set of surnames. This information can be useful for studying the current or historic distribution of surnames, and occasionally their origin. Surname maps are generally created using population lists, such as censuses, electoral rolls, taxation records and telephone directories.

Famous quotes containing the word map:
“When I had mapped the pond ... I laid a rule on the map lengthwise, and then breadthwise, and found, to my surprise, that the line of greatest length intersected the line of greatest breadth exactly at the point of greatest depth.”
—Henry David Thoreau (18171862)
