There is enough circumstantial evidence in the death record for me to believe "Mooscha" is my person of interest. He died at the right place, at the right time, and after visiting the business fair in Nizhny Novgorod.
I have just never heard the name Mooscha - not that I would have because I've seldom been exposed to Lithuanian/Russian names. The name just seems a little off to me. I'm going to put the name in a family genealogy, and I don't want a made-up name to appear in a report that will be kept for posterity.
Again, thank you for your interest.
