Crumiller is pronounced “Crumb-Miller.” It’s actually a portmanteau of Crum and Miller, which Susan’s parents both adopted.
Susan has continued the tradition in her family. She and her husband’s legal name, and their daughters’ last name, is Crumchau -> a portmanteau of Crumiller and Chaudhury. (Susan and Arastu both use their birth names professionally.)
Susan is extremely proud to be, in all likelihood, one of the only people in the entire world whose father and husband both changed their names. Hopefully Zohra and Sadia will continue the tradition!
