Aislyn Awley is Dom's wife, whom he met during his time studying at Hogwarts, they have two children together; Robin and Eliza Awley. Aislyn is a muggle born witch, it was for this reason that, due to their marriage, Dom was disowned by his family; though he has stated on many occasions that this was "no great loss".
Aislyn is a magizoologist, and thus goes on varous expeditions to far-off places during the summer and writes about her experiences and observations upon her return. Melissa and Dom live in a house in Hogsmede with their children, so that he can be close to his family during term time.
