_Mowbray Coheirs._--Collins in his _Peerage_ (ed. Brydges, 1812), says,
at p. 18., speaking of Thomas Duke of Norfolk:--
"In 15 Henry VII, he made partition with Maurice, surviving
brother of William Marquiss of Berkeley (who died issueless), of
the lands that came to them by inheritance, by right of their
descent, from the coheirs of _Mowbray_, Duke of Norfolk;"
and quotes, as his authority, _Commun. de T. Pasch, 15 Henry VII., Rot._
1.
The roll of the whole year referred to has been examined, without
finding any notice of the subject.
Should any of your readers have met with the statement elsewhere, it may
happen that there is some error in Collins's reference to his authority;
and a clue to the right roll, or any other notice of the division of
this great inheritance, will be acceptable.
