Ormrods per 100,000 of the population in North West England at the time of the 1881 Census

 

This map shows the number of recorded Ormrods per 100,000 entries in the 1881 Census.

It can be seen that there are large concentrations of Ormrods in the civil registration districts of Bolton and Barton upon Irwell.

More suprisingly there are also signigicant concentrations in the districts of Skipton, Settle and Lunesdale, away from the traditional Ormerod heartlands.
