ROBERT DE LISLE, son and heir, in 1264 obtained a charter offree warren in his demesne lands of Rampton and Wilbraham, co.Cambridge, and Nedging, Suffolk. As Sir Robert de Insula heattested a Cambridgeshire charter about the same time. He wassummoned for the campaign against Llewelyn in 1282.
He married, 1stly, before 1252, Mabel, widow of Hervey, baron ofStafford (died 1241), and daughter of Sir Robert DE MUSCEGROS,of Charlton, by Hawise, daughter and coheir of Sir WilliamMALET, of Curry Malet. Robert de Lisle and Mabel quitclaimed toJohn de Muscegros 10 librates of land in Kemarton, co.Gloucester, which Mabel had in free marriage from her father,and for this and 200 marks John gave her 20 librates of land inFinborough, Suffolk. Robert married, 2ndly, Alice. He died in1284. His widow was living in 1290. [Complete Peerage VIII:70,(transcribed by Dave Utzinger)]

Note: I have put Mabel's prior marriage in, but I am not sure ithappened, and I haven't changed any estimated birth dates forMabel to facilitate it happening. The CP entry for Herveydescribes his wife Mabel as daughter of Richard de Mucegros(sic.), who I believe was father of Robert de Muscegros. SinceHervey died in 1241, and Robert de Lisle may well have not beenborn in 1241, it is very unusual for a widow to marry as her 2ndhusband, a man who was not born by the time her 1st husbanddied! So I think that the Mabel who married Hervey de Staffordwas daughter of Richard and aunt of this Mabel who m. Robert deLisle.
