The Marquis of Grendon is an elderly man, born in 1077, who married as a young man to Bastria Eranne MacRorie, born 1084. They had no children, and she died of sickness in 1114. , but had no children with his wife. Aldrich grieved for many years, but in 1135, he married again, this time to Irdamiac Atavar, born 1112.
Grendon has powerful connections in the government, and does not hesitate to use them. He is, however, something of an outcast in noble circles, probably because the title of Marquis is normally reserved for children of royalty, and many hold the family rank against them.
If anything stands out about him, it's his appearance. He does not look his age - most who see him think he is at most 70 or so.
