“[W]hile to the common lawyer dos meant dower, in other systems it meant dowry: a gift to the wife, or to husband and wife, by the bride’s parents or other relatives. In England this was called the ‘marriage-gift’ or maritagium. Marriage-gifts were commonly made either to establish a cadet branch of a family or to assist a daughter who was not an heiress to make a good match.” J.H. Baker, An Introduction to English Legal History 310 (3d ed. 1990).
