James Jackson was an Anglican clergyman, best known as the author of an analytical index to the parish register of Brixworth, where he was vicar from 1735 to 1770.
His index is one of the earliest complete parish register transcripts and family reconstitution projects.
He married Elizabeth Benwell (buried 1754) of Henley-on-Thames and they had seven children: James was ordained deacon in 1725 and priest in 1725/6.
He probably lived at Reading immediately before arriving at Brixworth, as his index states that his marriage took place there, as did the baptisms of his three oldest children and the burial of his daughter Anne, who was “born when the Small-Pox appeared upon her Mother”.
It therefore includes much information about the origins and destinations of people who arrived in or migrated from the village during the 18th century.
