From her father's Wikipedia page. The entry for her (and her sister Aline) cited Cokayne, but the citation does not mention them. Cokayne's information is cited to support that they were illegitimate:"That both she and her unnamed sister were illegitimate is indicated by the fact that neither inherited anything from their father's great holdings. See: Cokayne, CP, X, Appendix H, 103". George Edward Cokayne, The Complete Peerage; or, A History of the House of Lords and All its Members from the Earliest Times, Vol. X, eds. H. A. Doubleday; Geoffrey H. White; & Howard de Walden (London: The St.Catherine Press, Ltd., 1945), Appendix H, p. 103, Familysearch (image page 963)
