Uses of heraldry for study and verification
The uses of heraldry, apart from its general significance in providing distinguishing symbols, are considerable. Heraldry explains much history and literature that is otherwise obscure. Heraldry on buildings, in manuscripts, and in paintings is of immense value for purposes of identification. It serves to link one person with another, to connect families, and to disclose origins of states and of institutions. The use of heraldry in connection with genealogy, from which it cannot easily be separated, makes easy to interpret much that was difficult to follow. In every building that contains armorial engravings or other pictures of arms, there is a concise contribution to the details of its background, one that gives a knowledgeable onlooker useful clues to its history.
In Scots law the place of heraldry is very precise. In England, on the other hand, it is more open to interpretation. To understand the latter is to gain an insight into the development of English law.
Similarity of arms does not always demonstrate identity of family. English laws of inheritance allow not only an estate but also a surname and arms to pass by eventual succession to individuals unconnected in blood with the original owner. Thus, in the families of Lytton and Carew and in branches of Trelawny, for example, instances occur in which possession of the name and arms is contrary to a blood relationship.
