Hi Al - thanks for your message.

I'm related to Christopher Schwarz and his wife Anna (surname unknown), of whom I have no information whatsoever. Their daughter Auguste Schwarz (born 06 Sep 1845 in Finckenstein, Kreis Rosenberg, West Prussia) married my 2nd-great-grand-uncle, Carl Charles Lange on 22 Oct 1868 in Finckenstein, Kreis Rosenberg, West Prussia.

I do not know if Christopher and Anna had any other children.
