I've been trying to track Samuel Soupcoff and his family for years. My grandfather had told me that the Pittsburgh Soupcoffs were related to his Pittsburgh Supkoffs, but he didn't know how. The Soupcoffs had come to America earlier than my Supkoffs, and I was trying to find the Soupcoff town of origin. But in most cases, they simply stated "Russia," although one of Samuel's brothers, in his name change application, said that he had been born in Bessarabia--and in other places he stated Germany. And Samuel's father went back to visit family and said he had been in "Podolian," which would be the Podolia Guberniya where my Supkoff (then Zubkis) family was living. But I wanted to narrow it down to a specific town to see its proximity to my family.
Because Samuel was famous, I thought that perhaps there would be more recorded about his origins. But he either claimed he was born in Russia or Pennsylvania. I looked in many (many) places. Since he lived in Salt Lake City for much of his adult life, I spoke to local experts at the Family History Library, but they couldn't think of resources beyond those I'd already checked.
Well, I found him. And whatever was scrawled on that passport application was a lie.

- Back in 2015, I wrote this post which shows that Samuel was a world-renowned mining engineer.
- In March 2016, I wrote about how Samuel's passport application had a letter of reference from the governor of Utah and and that his obituary mentioned his being a personal friend of President Hoover. Samuel's passport application had a scrawled place of birth, and I had thought that perhaps I had identified his place of birth.
Well, I found him. And whatever was scrawled on that passport application was a lie.
