As you say interesting that the Vaughans are mentioned in this posting
I am hoping to get to Hereford soon I would love to see these documents.
Presumably the numbers you quote are the Record Office Index numbers and if I quote these I should be able to look at them?

I do realise that they are not anything to do with William Henry Vaughan and Julia Hewlett, but that name of Vaughan gets everywhere.

JELF seems to have been a wealthy Gloucestershire family, so having members in the Clery is not a surprise. Branches ( possibly linked) appear in Ruardean / Sandhurst/Maisemore and Bristol

An example of the wealth / investments slightly further a field :-

Details of original mortgage granted to William Jelfe (Richard's father) in 1708 on security of lands in Ruardean, Glos. subsequent assignment of mortgage & transfer of property to Richard. As part of this agreement, some of the original mortgage was repaid.
Paper - written on 7 sides - some small holes in folds of final sheet - hardly affecting text
