What is the fine-grained topic of the following text: Helena Trant…so reminiscent of Helen Trent, whose vicissitudes on radio kept my generation enthralled, not to mention the ever so slight similarity to the name Trapp and all that that truly box-office name suggests; we are almost in the same neck of the woods, too, the Black Forest, There are three children.

Comparison and connection between Helena Trant's life and famous figures/stories.
