About the study

The Jelley One Name Study was started in 2000 after the death of my father Ronald James Jelley (1909-1999). He travelled to London from Buckinghamshire every week to write down all the Birth, Marriage & Death references from the GRO up to 1983 and I felt it would be a shame to not put the information to good use.

Variant names


Name origin

A Diminutive of Julian. For my study there are three pockets of the name all going back to the 1500's. Leicestershire, Northamptonshire, Rutland.

Surrey & Sussex.


Distribution of the name

There are three main areas of the Jelley/Jelly surname.


Leicestershire, Northamptonshire, Rutland

Somerset to South Wales

With the start of the DNA Project I hope to make more sense of the possible connections.


Births Marriages & Deaths from GRO Index Total 17,000.

Parish Register material for all Counties amlunts to a vast amount of information.

Many Family Trees all hoping to tie up at some stage.

Many contacts on these various trees in UK, Australia & New Zealand.

USA is another story yet to unfold


A DNA project has just been initiated in the hope that the many sections of the Jelley & Jelly surnames can somehow come together.
