Richard FitzAlan d'Arundel, Knt. - Problems with this entry

Hello,
There seem to be some problems with this entry.
First, the surname of the person in question is "FitzAlan", not "FitzAlan d'Arundel". His father's name was John FitzAlan, and his *title* was "Baron Arundel". Upon John's death the barony passed to his eldest son, also named "John FitzAlan" (1364-1390), thence to his eldest son (also "John FitzAlan", 1385-1421), and so on. To be clear: "Arundel" was the title of the barony, not properly part of their particular surname.

Second, "Knt" is a non-standard title, and discouraged in usage on Geni (and elsewhere). If indeed he was a knight, he should properly be styled "Sir Richard FitzAlan". Having said that, I can't find any mention of him being knighted in my resources (but it would not surprise me if he had been so). If you have a source for the assertion of a knighthood, please provide it.
Thank you.
