Looking at the list it would appear that
Conyers and Furnivall will likely be revived through the death of a co-heiress.
If the co-heirs agreed a few baronies could come out of abeyance
grey de ruthvin
Audley
Botetourt
Botreaux
Stanley
Hastings
North
The Scottish peerages of
Breadalbane and Falconer of Halkerton would appear to be dormant with heirs who might be able to prove their title.
Since some of the English baronies listed above and in abeyance have the same heirs one would like to feel that a family agreement would allow some of the titles to be shared within a group of cousins.
