I am also researching Charles Boldt. I dont know if this is the same Charles Boldt that you are researching but I have named my son Boldt Lindfors. My almost 94 year old great-grandma was telling me names from our history and when she told me the name boldt i loved it so i named him it. She told me that he was like a bodyguard for whoever was in power in Germany at the time and he had a brother named August. She remembers a lot at her age and seems to remember him pretty good so she might be able to answer any questions if its the same Charles Boldt and if you can tell me anything you know or guide me in the right direction. Maybe we can help eachother.
