willer

One who wills; who causes by an act of will or willpower.

For he sayeth vnto Moses: I wyll haue mercy on whom I haue mercy, and haue compassion on whom I wyl haue compassion. It is not therfore of the wyller, nother of the runner, but of God the shewer of mercy.

[…] he that shall act, or cause that Law to be executed, makes himself the Commander, or willer of it, which was originally the Will of others:

One who leaves an inheritance by writing a will.

The father died. The females three Were much in haste the will to see. They read, and read, but still Saw not the willer's will. For could it well be understood That each of this sweet sisterhood, When she possess'd her part no more, Should to her mother pay it o'er?

For if the actuality of a last will and testament takes effect only with the fact of the death of the willer and testator, then strictly speaking, what decides inheritance is not the will of the giver but his decease.

A surname.
