Visitation (Cheshire, 1580, Mallpas) suggests that Sibill had a daughter Agnes who was the Agnes de Malpas who married a Pulesdon and was mother of Roger de Pulesdon (presumably only the one shown as having married Agnes below if that connection is wrong). We hope to investigate this further in due course.
It is likely that Ridley came into this family through marriage with the Ridleys of Ridley (# see here #). We hope to find out more on this in due course.
The following comes mainly from Visitation (Dugdale, 1664, Egerton of Shaw).
b. Elizabeth Egerton (d young)?
