Are you sure this was never spelled Dorsz/Durst/Drost/many variations & misspellings. I ask because both Victor and Stella are names in our family....Dorsz and Michalski. The surname Dorsz is spelled different from birth record to birth record. These families (along with Rusinski and Flak) moved from Buffalo, NY and lived in and around Detroit. We have pieced together Jan Dorsz back to immigration, have his parents names, we think, but none of his siblings. Let me know what you think.
