Petrus Patricius in Excerpt. Legat. p. 27 [ed. Paris; p. 19, ed. Ven.; p. 129, ed. Bonn]. If it should be thought that γαμβρος signifies more properly a son-in-law, we might conjecture that Constantine, assuming the name as well as the duties of a father, had adopted his younger brothers and sisters, the children of Theodora. But in the best authors it sometimes signifies a husband, sometimes a father-in-law, and sometimes a kinsman in general. See Spanheim Observat. ad Julian. Orat. i. p. 72.
