Spatial Analysis of Surnames
- What’s in a name?
- Individual surnames as spatial phenomena.
- Groups of surnames as spatial phenomena.
- Surnames as cultural phenomena.
What’s in a surname? Everyone has one! Informed by culture- this is invariably spatial. Generally “patrilineal” that is inherited from your father. There are exceptions to the above.... ....however, my interests lie in general observations

Individual Surnames as Spatial Phenomena R
Individual Surnames as Spatial Phenomena: Applications For each name we can produce the following for both 1881 and 2001: - Where it is most commonly found. -The spread/ density of the name. -Whether a name is characterised by a single core area or multiple core areas. This information has fostered collaboration with geneticists who are interested in the link between our ancestral genes and surnames. Spatial analysis of surnames enables: - The targeting of sampling. - Validation of samples. - Prioritisation of sample analysis.
Individual Surnames as Spatial Phenomena For this research names need to be filtered by: - The spread of the name- achieved with a convex hull. - The frequency of the name (freq. > 100 removed). - The density estimates are also weighted by the location quotient. Software - R was used for the majority of this analysis. - It is much quicker in this context. All this in less than 1 second: MySQL Database query-> Convex hull-> Area of hull-> KDE-> Extract by mask->Contour-> Area of Contour-> Export results. - Hawth’s Tools in ArcGIS provides an alternative. Much, much slower. - RPyGeo enables the advanced geoprocessing modules in ArcGIS to be called from R. It provides the best of both worlds. R is pretty bad at a lot of spatial stuff- especially converting one spatial data type (such as a line) to another (such as a polygon).
