You must be related to a Julian Zmroczek who was living in Michigan and moved to Florida. I was trying to track down any relatives he might have had in the US but didn't have any luck. I did get his application for Social Security and his parents had the same names as your grandparents. My father's name was Lukasz Zmroczek. He was born in the State of Kaminetz Village of Tonaruda in 1913 and migrated to the US in 1913.You can contact me at my email address if you want to it is
ichque10@aol.com. I think this will be an easier way for us to communicate.
