I have sufficient coverage (although incomplete) of the records to allow an examination of where the known marriages took place, in 50 year slices, between 1550 and 1950. Outside that date range I do not have enough records to make any examination meaningful, and in fact the range 1901-50 is barely representative.

A series of maps are presented below, with the Glanville marriages identified by white spots - the larger the spot, the more marriages took place there.

Known Errors

• I have used my own experiences and judgement (which is not perfect) to decide which spelling variants to include / exclude as "Glanvilles". Phonetic spelling, transcription errors, original document mistakes etc etc etc conspire against exactitude in my analysis.
• Not all marriages that must have taken place have been identified.
  For example, baptismal and census records inform of married Glanvilles for whom the marriage record is yet to be found. Hence there are more marriages than identified marriage spots on the maps.
• Many of the marriages are of Glanville woman, and some of those will have been Glanvill(e) widows remarrying in their previous married name - i.e. they were not born Glanvilles
