In 1896, my great grandfather, Rudolf Meyn, and his mother Charlotte Meyn, emigrated from Hamburg Germany and settled in Rock Rapids, Iowa with her brother. I believe her brother's last name was Bunte. Charlotte Meyn remarried and then died around 1900 and was buried in Rock Rapids, Iowa. I'm looking for any information leading to marriage or death certificates or any other information. Any suggestions would be greatly appreciated.

Thank you!
