♀Isabel FitzRoy

Isabel FitzRoy was the twenty-fourth great-grandmother of Nancy Jane Blanchard (1929–2006), through her son William FitzRichard.

Isabel married Richard FitzIves, who is said to have been a knight of Degembris, in the parish of Newlyn East, Cornwall, and their son William FitzRichard became a knight of Lanisley, in the parish of Gulval, Cornwall. Her surname means “son of the king” and was given to royal children born outside marriage. She is alleged to have been an illegitimate daughter of John, King of England, by an unknown mistress, but the descent is unproven and her parents are not known.

Notes

Sources

Isabel’s marriage and her son are from Douglas Richardson, Plantagenet Ancestry, 2nd edition (2011), vol. 1, pp. 173–174, a compiled genealogy, in the descent chart that opens its account of Agnes Longland. Isabel and Richard appear there by name only, without an entry of their own; Richardson gives the Fitz Ives family in full in vol. 2.

Her parentage

The chart on p. 173 sets “JOHN, King of England, by an unknown mistress” above Isabel’s name. At p. 41, among the king’s children, the same author is more careful: “Alleged illegitimate child of John of England, by an unknown mistress, i. ISABEL FITZ ROY, married RICHARD FITZ IVES, Knt., of Trenoweth-Chammon (in St. Keverne), Cornwall.” Because the descent is given only as alleged, King John is not shown on this site as her father.

Dates

No date is given for Isabel’s birth, marriage or death. The nearest date in the family is her great-great-great-granddaughter Agnes Longland’s birth about 1370, from her age of ten in 1380.
