Perhaps you're referring to a discrepancy (or discrepancies) in the lineage of James Claypoole, Sr.
An article by Charles M. Hansen appeared in the April 1992 issue of The American Genealogist (pages 97-107) "THE DESCENT OF JAMES1 CLAYPOOLE OF PHILADELPHIA FROM EDWARD I, A Correction of the Lineage" which mentions errors in previous accounts of James Sr.'s royal descent:
"A letter written in 1707 by one of his brothers proves that James Claypoole, a Quaker immigrant to Philadelphia in 1683, was of a gentry family seated at Northborough in co. Northampton, England.However, the descent claimed in other sources for him from King Edward I has never been properly documented and, in its published versions, contains a number of errors.Rebecca Irwin Graff mentions the descent, but her account of the generations passing through the Wingfield Family is garbled (Genealogy of the Claypoole Family of Philadephia 1588-1893 [Philadelphia 1893], hearafter Claypoole Fam., pp.151-52).Charles H. Browning confuses Robert Wingfield of Upton, who died in 1576, with his cousin, Sir Robert Wingfield, who was present at the Field of the Cloth of Gold in 1520 (Americans of Royal Descent, 7th ed. [Philadelphia 1911] pp. 91-92).This fusing of the two Roberts is found in several other secondary sources (including Virginia Magazine of History and Biography 60 : facing p. 320) and is derived from Mervyn Edward, Seventh Viscount Powerscourt (Muniments of the Ancient Saxon Family of Wingfield [London 1894], hereafter Wingfield Fam., p. 35).
The Wingfields are included in Walter Lee Sheppard, Jr., ed., The Magna Charta Sureties, 1215, 4th ed. (Baltimore 1991), hereafter MC Sureties, pp. 25-26, line 21.The three generations that figure in James Claypoole's descent from Edward I are summarized:
9ELIZABETH GOUSHILL, living 1414; m. Sir ROBERT
10Sir HENRY WINGFIELD, d. bef. 6 May 1493, Governor of
Orford Castle; m. ELIZABETH ROOKES
11Sir ROBERT WINGFIELD, d. Castre, co. Northampton
4 Feb. 1575, present at the Field of the Cloth of
Gold 1520; m. MARGERY QUARLES
Besides a few errors in dates and the fact that Robert Wingfield (#11 above) is again confused with his cousin, Sir Robert Wingfield, there appears to be a more serious problem with the line at this point, one of chronology.The editor noted that "The chronology is very long between generations 9 and 11.These three generations need more research before complete acceptance" (MC Sureties p. 26).Additional research determined that Elizabeth Goushill was born about 1402, so 174 years separate her birth from the death of her grandson Robert Wingfield in Feb. 1575/6.This chronolgy suggested the possibility that two Roberts had been combined into one, and that the Robert Wingfield named as son of Sir Henry Wingfield was not the Robert Wingfield who died in 1575/6.
In attempting to resolve this problem, I reviewed a number of published pedigrees of the Wingfields, including: Sir Henry Ellis, ed., Visitation of Huntingdon, 1613, Camden Society Old Series 43 (1849):128; Visitation of Rutland 1618-19, Harleian Soc. Pub., Visitations 3 (London 1870):32; Walter C. Metcalfe, ed., Visitations of Northamptonshire, 1564 and 1618-19 (London 1887) p. 204 (appendix); E. M. Deming, "Pedigree of Wingfield," Suffolk Institute of Archaeology and Natural History 7 (1891):57-67; and Burke's Landed Gentry, 17th ed. (London 1952) pp. 2762-63.All of these listed the Robert who died 1575/6 as son of Sir Henry Wingfield.But none of the visitations can be considered strictly a contemporary source, while the secondary sources do not include full citations.
A search through the various calendars of documents published by the Public Record Office (hearafter PRO), the wills of Sir Henry and Robert Wingfield and the Inquisition Post Mortem (hereafter Inq. PM) of Robert (copy obtained from PRO) did not provide evidence that would conclusively solve the problem.Therefore, in what usually should be taken only as a last step when dealing with a gentry line, I wrote to the College of Arms to see if the records there included anything that would help in the solution.This effort proved successful and I received a transcript of a funeral certificate, executed by Robert's son in 1576, wherein he stated that his father was a son of Sir Henry Wingfield.This then was solid contemporary proof of Robert's parentage and, as will be shown, the apparent chronological problem was caused by (1) Sir Henry's birth when his mother was close to forty, (2) the birth of Henry's son Robert by a second marriage when he was about fifty, and (3) the relatively great age for the period attained by his son.
DESCENT FROM EDWARD I
In the following lineage of James Claypoole from Edward I, the initial generations are based on entries from The Complete Peerage, which cites primary sources (G. E. Cokayne, ed., new ed. [London 1910-59], hereafter New CP).For the later generations contemporary sources have been cited to prove each link.The brief biographies are included to illustrate the transition in roles and status as the line passes from the king through the higher nobility to the knightly class, and then through the landed gentry to the Quaker merchant, James Claypoole."
