Cousins,
Ancestry.com also has Clemence de Arcy who married Henry Pinel as being
Joanna's mother. I think because the names are so close--Clemence Dauntsey
and Clemence de Arcy--that there is some confusion over who was Joanna's
mother. I will check some other sources on this. It is fascinating,
especially since many older books ("Merion In The Welsh Tract", etc.) listed
Joanna's mother as Agatha Ferrers.
I would like to check Cokayne's Complete Peerage on this, so I guess I should
make a trip to the Newberry Library in Chicago soon!
