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.

Title	Date of Creation	Date of Birth of incumbent	Notes
Baron Mowbray Baron Segrave	1283 1295	1991	Co-heirs are four sisters born 1982, 1983, 1987, 1988
Baron Willoughby de Eresby	1313	1934	Co-heirs two first cousins once removed (b. 1965 and 1978)

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:

Title	Date of Creation	Notes
Baron Conyers Baron Fauconberg	1509 1295	Heirs are two sisters, born 1954 (unm) & 1955. Upon the death of the elder sister, there will be one heir only.
Baron Furnivall	1295/1318	Heirs are two sisters, born 1933 (unm) & 1935. Upon the death of the elder sister, there will be one heir only.

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).
