From the City of Westminster Archives, 16,818 index records for Westminster wills and probates with links to images of the originals handwritten in Latin, later ones in English. There are also modern cards, often referring to inventories, with scant information beyond name and date.
The bar chart shows the number of records in 20 year periods centred on the date shown. The gap at 1650 reflects the drop during the Cromwell Protectorate. Only 23 entries are for the 1650s with none for 1653 and 1654.
