Thank you so much for your prompt reply. I have been trying to link Vaclav Richter to the Koprava or Kopriva family. I'm particularly interested in learning if Anna died not long after the birth, as well and Vaclav then married Barbara Koriva, perhaps Anna's sister (?), I have evidence that another child named Vaclav Richter was born in Kladno in 1871 to parents Vaclav Richter and Barbara Kopriva. (I'm aware that names were often given to subsequent children if the first child by that name did not survive.) Unfortunately some of the subsequent relevant Kladno birth and marriage records do not seem to be available online yet. However, any further help will be deeply appreciated. Thanks again!
