My grandfather, Alexis Chester Wojeciechowski, was born in Warsaw, Poland / East Prussia in 1889 and reportedly left with his mother in the middle of the night, due to strife in the country. He settled in Detroit, MI, marrying Anna Malinowski of Buffalo. Family legend has it that he was related to Stanislaw Wojciechowski, perhaps a nephew, but I have not been able to find any information on his ancestors.
In the 1940s, the family changed their name to Wolff (some became Wolffe).
Any clues here?
