Surname Distribution Maps
Surname Distribution.
In tracking down the origins of TROTT surnames and variants, it is essential to plot the distribution in various types of records such as those from Family Search, the IGI (International Genealogical Index), the census returns and the many other indexes that are now to be found. For England, Wales and Scotland, there are census records from 1841 through to 1911. These are available on a number of websites: Family Search (www.familysearch.org), Ancestry, Find My Past, GenesReunited and Scotlands People.
Plotting distributions in the 1881 Census has been made easy by the issue of Steve Archer's Surname Atlas CD. The maps below have been produced from that CD and show (apart from the first) the frequency per 100 thousand population in each County or Poor Law Union (equivalent to Civil Registration District).
Comparative distribution of TROTT (1,965), TRATT (169), TRETT (189) and TROUT (579) in 1881 Census. (NB actual numbers in brackets.)

The distribution is very similar to TROTT, but far less common,showing that the names probably have a common origin.
