Henley Holy Trinity is located 25 miles south east of Oxford. The parish was planned as a chapelry of Rotherfield Grey St Nicholas, and was originally referred to as Rotherfield Greys Holy Trinity, but later became a parish in its own right.
The records were originally deposited in the Bodleian Library by Rev. APJ Le Sueur victor of Henley Holy Trinity in 1983. The material was then transferred to the Oxfordshire History Centre. Further records were deposited as Acc 6782 in August 2019.
The collection was re-catalogued by Alison Smith in December 2011 with additions in August 2019. An appendix gives the concordance of old Bodleian Library catalogue references with the new Oxfordshire History Centre references.
