Alianora ‘Eleanor’ (FitzAlan) St. George - Disputed origins

< Stirnet: StGeorge1 > A. John St. George (dvp) m. Matilda Cogshall (dau of Sir William Cogshall) i. Sir William St. George of Hatley St. George (d 1472-3, MP) MGH identifies William's wife Alianora as dau/coheir of Sir Richard Arundel. Visitation & BE1883 identify her as ... m1. Elionor Arundell (dau/(co)heir of Sir William Arundell)

What is the evidence favoring Sir William Arundel as he4 father other than Visitations?
