Obviously the English names (Gilmore and Bolt) have been the easiest to trace (most of the records are in English) But the Ukrainian and Polish names are an absolute nightmare! And I'm afraid my rudimentary Ukrainian and Polish language skills aren't up to speed.
The most frustrating part of my search so far? My Ukrainian great-grandfather (who couldn't read or write) landed in Quebec, where his naturalization record lists his name as Souvchok. My good friend Serendipity helped me find THAT one!
And my Polish great-grandparents embarked on their journey in Bremen, Germany. I can just imagine the mishmash of mistakes in THOSE records!
