I hope you still read this forum, since the message I'm posting to is about 2 years old.
My g-grandmother was Kley by baptism, but she was born in Brazil. Her father, Jacob Kley immigrated to Brazil from Germany, but I couldn't find his home city. This is the only data I've got about him: deceased at Porto Alegre, RS, Brazil, in 1910. He married Luise Mose in Brazil (German, her 3rd marriage). Jacob was son of Christian Kley and Anna Eva Purpur.
