Notes for Isabel Deincourt
CP: Apparently dsp. however some evidence has been found that she had a daughter Joan who marrried Brian de Thorhill. cf Baildon & the Baildons by William Paley Baildon, Chapter Eleven - The Fitzwilliams of Emley and Sprotborough, page 355; Testamenta Ebor. Vol. 1, No. 50] However Clay in “The Family of Thornhill” ,YAJ 29, p. 306, note (2), rules this out for lack of evidence and other difficulties.
The second unknown was her ancestry. This has been supplied by Louise Staley (soc.gen.med, 23 Sep 2004) as Sir Edmund Deincourt, 1st baron Deincourt (d. 6 Jan 1327) and Isabel Mohun.
