Thank you for the new information. I will definitely follow up with the embassy. I had some questions, though.
Where can I gain access to these old intelligence files? Where and how did you find them? I've been scouring databases all over the internet, but have never gotten a hit on his name, save Ellis Island records, a wedding notification, and a blurb about his being released from an English dentention camp (for being an "enemy alien") in 1914.
Also, I've been trying to confirm that Plaska and Prague are the same thing, but so far all I've been able to find on that score is a Hotel Plaska on Plaska street in Prague. Where can I find this information?
As to when the title was awarded, family lore claims that his father (also a doctor) was the one awarded the baronage. There is no name given for his father, but he had at least two siblings. Anna, and Alfred.
