Historically it has been identified that the Jessop family name originated in Yorkshire before spreading from right across England - for more information check out Jessop under Name Meanings.

Current research identifies our line of the Jessop family as originating in Suffolk abt 1750. The Our family line is first found in the Blything Hundred of Suffolk in the late 1600's. It is most likely related to the Jessops of the Mutford Hundred, specifically Francis Jessop - a Cromwellian deputy of William Dowsing - who was living in Beccles, Suffolk in 1644. There were other Jessops were located in Suffolk from about 1500, and further research is underway to link the linesas early as 1500, but there is no clear relationship between those lines, nor is there any established relationship between the Suffolk Jessops and the Yorkshire Jessops.

The earliest known confirmed member of our Jessop line is Charles Jessup, who resided in the small hamlet of Cratfield. However little Robert Jessup of Huntingfield. However little detail is known of the Jessup family before the migration to Australia of his son John Jessopline until his grandson John Jessop migrated to Australia in 1838.
