User:Newprogressive/Peerage titles with no heirs

Titles likely to become dormant
Titles where there is no known heir, but it cannot conclusively be determined that no heirs exist. Titles that may be in dispute are not listed here as there are known heirs. Titles where an heir is thought to exist but cannot be confirmed are not listed here, instead these are listed in the main lists with a note stating that an heir might exist. Titles in dormancy are not listed here, but will be listed in the extinction lists with a note.

Titles likely to become abeyant
There are some titles with two (or more) heirs were division is possible through female lines. Most commonly these are Baronies by Writ created in the Peerage of England.

Titles likely to come out of abeyance
Whilst it is uncommon for the Crown to terminate an abeyance, a few peerages in abeyance will naturally come out of abeyance when only one co-heir survives. This is likely to happen for:

Titles with only 1 heir aged 50 or more
Subsidiary titles are not listed. All titles listed here have one heir unlikely to produce a male heir themselves. Some titles may have a young incumbent who may yet produce heirs (e.g. Earl of Craven).

Other titles under threat
The titles listed in this section are titles with more than one heir that seem likely to become extinct. Often the heirs are all aged over 50, but titles with slightly younger heirs may be listed, particularly if the younger heir is unmarried. Titles with a young incumbent but older heirs will not be listed. Subsidiary titles are not listed.
