Many family historians rely on published pedigrees such as John Burke‘s 1833 Genealogical and Heraldic history of the commoners of Great Britain and Ireland. Unfortunately sometimes Burke got it wrong.
My Mainwaring forebears are included in Burke’s 1833 family records, a genealogy of the junior houses of British nobility, which records family origins, surnames, events, and locations of about 300 British families; some are accompanied by coats of arms. The records have been digitised and indexed by Ancestry.com. The incorrect relationships are included in at least 28 public family trees on ancestry.com, presumably based on Burke’s error.
The entry for my seventh great grandparents reads:
Edward Mainwaring, of Whitmore Hall, bapt. 25 Aug. 1681, m. 1st Jemima Pye, second dau. of Edmund Pye, of Farringdon, Berks (see Burke’s Landed Gentry), by Anne , his wife, dau. of Lord Crewe, of Stene, and by her, who was buried 22 August 1721, had issue, …
When I started to look at the text of the marriage settlement for Edward and Jemima I became a little confused. Burke’s has combined mother and daughter into one person: Jemima was the daughter of Anne Rider formerly Pye nee Wright (c 1660-1731) and granddaughter of Anne Wright nee Crew (1637-1707); Jemima was thus the great granddaughter of Lord Crewe of Stene, 1st Baron Crewe.
The settlement was dated 15 March 1708 and was between four groups of people:
- Edward Mainwaring of Whitmore, only son and heir of Edward Mainwaring deceased by Bridgett his wife, of the first part;
- The Right Honourable and Right Reverend Nathaniel Lord Crewe, Baron of Stene, and Bishop of Durham, Henry Pye of Faringdon Co. Berks Esquire and John Conyers of Walthamstowe Co. Essex Esquire, Executors of the will of Dame Anne Wright of Dagenham, of the second part,
- Anne Rider late wife of Edmund Pye Esquire of Faringdon and Jemima Pye, the daughter of the said Anne Rider and Edmund Pye of the third part, and
- the Honourable Edward Cartaret of the Middle Temple and Carew Hervey, alias Mildmay, of the fourth part.
Dame Anne Wright of Dagenham was the daughter of Lord Crewe of Stene. She was the sister of the Right Honourable and Right Reverend Nathaniel Lord Crewe, Baron of Stene, and Bishop of Durham. She died in 1707 and her will was proved on 24 March 1708.

Anne Crew, born about 1637, married Henry Wright on 23 March 1658. Wright was a physician, son of Laurence (Lawrence) Wright, also a physician, at one time physician to Lord Protector Oliver Cromwell. Laurence Wright died in 1658. Shortly afterwards, on 10 April 1658, Cromwell made Laurence’s son Henry a baronet. This honour was disallowed – it didn’t seem Wright – when the monarchy was restored in May 1660, but on 11 June 1660 Henry Wright was AGAIN created a baronet by King Charles II. Henry and Anne Wright had two children, Anne and Henry (1662-1681). Henry junior died unmarried and on his death the baronetcy became extinct.
Anne Wright, the daughter, married Edmund Pye on 4 March 1678/9 at St Giles in the Fields. Pye was a medical doctor, the son and heir of Sir Robert Pye of Faringdon, Berkshire. Edmund Pye was born in 1656 and died about 1703 of smallpox at Knotting, Oxfordshire. His wife Anne remarried, to William Rider or Ryder. She died in 1731. [Edmund Pye’s will probated 3 January 1704 PCC Will Registers; Class: PROB 11; Piece: 480. Anne Rider’s will probated 2 March 1731 PCC Will Registers; Class: PROB 11; Piece: 650]

Edward Cartaret was Jemima Pye’s second cousin. He was youngest of four children. His mother died at the time of his birth. Edward’s father, Philip Cartaret, was killed in the Battle of Soleby when he was six months old, along with his maternal grandfather, Edward Montagu, Earl of Sandwich. Edward Cartaret, together with Carew Harvey, were provided for in the marriage settlement of Edward Mainwaring and Jemima Pye in the case of failure of male issue of the marriage.

While I understand the family connection of Edward Cartaret, I am not sure how Carew Harvey alias Mildmay is related. He was a neighbour of Anne Rider formerly Pye nee Wright in Essex and was appointed Sheriff of Essex in 1712. Perhaps her estate of Dagnams was encumbered in some way to him.
I have not been able to find out much about William Rider. When Anne Rider formerly Pye nee Wright made her will in 1722 she described herself as the wife of William Rider and left him an annuity of one hundred pounds per year during his lifetime. She bequeathed one thousand pounds to her grand daughter Jemima Mainwaring as promised her son in law Edward Mainwaring. There were other bequests but her residuary legatee was her much esteemed friend and relation Edward Carteret, that is her first cousin once removed.

William Rider was also involved in several other court cases.
Although John Burke’s genealogy made a small error in confusing the generations, overall it is a very useful source and a terrific starting point for tracing the family trees of the families he documented. The genealogies would have been painstakingly compiled and of course without the databases and digitised records we rely on today. As with anybody’s research, Burke’s genealogies need to be verified against available documents which for this period include marriage settlements and wills. Perhaps also court cases.
