Aha, thank you. And yes, everyone had dropsy, including Fritz in that last year of his life. It's a very non-specific medical term and just means fluid retention, which has many causes. One is congestive heart failure--which, of course, is my guess for what Fritz died of. Googling suggests tuberculosis can, in some cases, also play a role in heart failure. Sympathy of their fates striking again? Or limited diagnostic evidence? Who can know?
