All persons who have descended from a common ancestor. Offspring; progeny; descent; lineage; lineal descendants. In this sense, the word includes not only a child or children, but all other descendants in whatever degree, and it is so construed generally in deeds. But when used in wills, it is, of course, subject to the rule of construction that the intention of the testator, as ascertained from the language used by him; and hence issue may, in such a connection, be restricted to children, or to descendants living at the death of the testator, where such an intention clearly appears.
