A great judge, who died but a few years ago, repeats language which would have been equally familiar to the lawyers of Edward or of James. Baron Parke, after laying down that in general a party is not required to make profert of an instrument to the possession of which he is not entitled, says that there is an exception "in the cases of heir and executor, who may plead a release to the ancestor or testator whom they respectively represent; so also with respect to several tortfeasors, for in all these cases there is a privity between the parties which constitutes an identity of person." /4/ But this is not all. The identity of person was carried [350] farther still. If a man died leaving male children, and owning land in fee, it went to the oldest son alone; but, if he left only daughters, it descended to them all equally. In this case several individuals together continued the persona of their ancestor. But it was always laid down that they were but one heir. /1/ For the purpose of working out this result, not only was one person identified with another, but several persons were reduced to one, that they might sustain a single persona. What was the persona? It was not the sum of all the rights and duties of the ancestor. It has been seen that for many centuries his general status, the sum of all his rights and duties except those connected with real property, has been taken up by the executor or administrator. The persona continued by the heir was from an early day confined to real estate in its technical sense; that is, to property subject to feudal principles, as distinguished from chattels, which, as Blackstone tells us, /2/ include whatever was not a feud.
