This relationship is given by Keats-Rohan (p. 508) and by the Sussex VCH (9:212).

This relationship is given by Rosie Bevan in a contribution to “Corrections to KSB Keats-Rohan’s Domesday Descendants”, citing Elvey (p. xlxii).

Evidence
De Lisle and Dudley (no. 62). This quitclaim, apparently from around 1207, is witnessed by Simon de Echingham and his brothers William and Henry. I am not sure it refers to this William's family. See also nos. 67, 94, 120.
