his younger brother Alexios. Marriage and family In , John married Maria Doukaina, daughter of the protostrator Michael Doukas—a brother of Alexios I's empress, Irene Doukaina. His wife's name is only attested while she was a nun, so it may represent a monastic name, rather than her birth name. The couple had five children; all of whom died early before their parents. Only the name of a son, Alexios, is known. Some time after 1130, John and his wife became monks, with John assuming the name of Ignatios. He tore down his father's palace and in its stead erected a monastery dedicated to the Holy Trinity, under the name of Euergetes ("the Benefactor"). Their last child probably died , which therefore is also the earliest possible date for the deaths of John and his wife.
