Constance had short white hair and light skin. In her picture taken with Clive she wore a black shirt, a pink skirt, a yellow shawl with a red rose, and numerous rings on her fingers. She appears to have been wheel-chair bound.
Constance was presumably a philanthropic and kindly individual seeing as she adopted Clive and left her entire fortune to him.
Constance adopted Clive after the death of his parents and raised him until her death five years later, leaving her entire fortune to him.
