This is a list of people with peerages of the United Kingdom created under the Life Peerages Act 1958 and Lords of Appeal in Ordinary (whose life peerages are created under the Appellate Jurisdiction Act 1876) who are closely related to one another, either by blood up to the degree of third cousins, or by marriage or cohabitation. This list is ordered by the antiquity of the earliest title each family has.

Maugham married Romer's sister, Helen Mary in 1896. He was later appointed Lord High Chancellor of Great Britain in 1938 and elevated to be Viscount Maugham, of Hartfield in the County of Sussex in 1939 on his retirement, as was customary. Romer married Anne Wilmot Ritchie, an elder daughter of the aforementioned first Baron Ritchie of Dundee. Their life peerages are

Four generations of the Hurd family have sat as Conservative MPs. The two middle generations have been given life peerages (Lord Hurd of Westwell notably serving as Foreign Secretary under Margaret Thatcher and John Major), and the youngest married the daughter of The Most Hon. the Marquess of Lothian and The Rt. Hon. the Lady Herries of Terregles in 2010. Lord Lothian also sat as a Conservative MP, and was given a life peerage upon retirement from the Commons. Despite already succeeding to his titles, he did so after the House of Lords Act 1999 removed the automatic right of hereditary peers to sit in the Lords, and so required a life peerage to be able to sit there. Lord Lothian married the 16th Lady Herries of Terregles in 1975. Her elder sister, the 14th Lady, married the cricketer Colin Cowdrey in 1985. Cowdrey was given a life peerage by outgoing Prime Minister John Major in 1997.

Quintin Hogg, 2nd Viscount Hailsham disclaimed his hereditary peerage in 1963, allowing him to take up a seat in the House of Commons. He was later given a life peerage in 1979 when he was appointed to the role of Lord High Chancellor of Great Britain. His daughter-in-law was likewise ennobled for life as was her father. The 3rd Viscount was also given a life peerage, which enables him to sit in the House of Lords following the House of Lords Act 1999, which automatically excludes most hereditary peers. The life peerages are

• Baron Boyd-Carpenter, of Crux Easton in the County of Southampton (1972,^[31] Conservative);
• Baron Hailsham of Saint Marylebone, of Herstmonceux in the County of Sussex (1979,^[32] Conservative);

The two daughters of the 8th Marquess of Londonderry connect two life peers; through marriage in one case through descent in the other.

Lord Londonderry's younger daughter Lady Annabel Vane-Tempest-Stewart married Sir James Goldsmith (knighted in Harold Wilson's so-called 'lavender list'); one of their sons, Zac Goldsmith, was given a life peerage by Prime Minister Boris Johnson to enable him to stay on in the Cabinet after losing his Richmond Park seat in the 2019 snap General Election. The titles are

• Baron Rayne, of Prince's Meadow in Greater London (1976)^[35]
• Baron Goldsmith of Richmond Park, of Richmond Park in the London Borough of Richmond upon Thames (2020)^[36]

Lord Oakeshott of Seagrove Bay is apparently closely related to Lady Bottomley of Nettlestone, but it is unclear how exactly. Lord Hunt of Chesterton is related in the male line to John Samuel Hunt, as was Lord Hunt of Hawley, although this relation is very distant.

Members of the O'Neill dynasty (whose members hold the hereditary peerages Baron O'Neill, of Shanes Castle, in the county of Antrim (1868) and Baron Rathcavan, of The Braid in the County of Antrim (1953), and who are distantly related to the Chichesters (headed by the Marquess of the County of Donegal), Captain Terence Marne O'Neill and Onora Sylvia O'Neill were both ennobled as life peers. They are second cousins, sharing Edward O'Neill, 2nd Baron O'Neill as an ancestor. Terence was a leader of the Ulster Unionist Party and antepenultimate Prime Minister of Northern Ireland from 1963 to 1969. He was followed in these roles by his 8th cousin James Chichester-Clarke. Onora is a distinguished philosopher, former President of the British Academy, and member (and honorary member) of many other learned institutions including the Royal Irish Academy.

Chichester-Clarke was later ennobled with the title Baron Moyola, of Castledawson in the County of Londonderry (1971, Ulster Unionist Party)

Both Barnett Janner (1892—1982) and his son, Greville Ewan Janner (1928—2015), served as Members of Parliament for Leicester West, Greville directly following his father. They were both subsequently ennobled with life peerages, which are

Just under a year before succeeding to the Earldoms, Robert Lindsay (then styled Lord Balniel) was given a life peerage. It is notable that he entered the House of Lords in this way, as he could conceivably have entered by writ in acceleration using one of his father's junior titles (such as the Wigan Barony, or even the Lindsay and Balniel Lordship of Parliament, with which was then styling himself). Two of his first cousins were also ennobled for life, Baroness Manningham-Buller being the second daughter of Rt. Hon. Viscount Dilhorne, first holder of the most junior viscountcy. The titles are
