I posted to this thread a fews years back regarding my grandmother Louise Lukowski. Seems there were at least 3 or 4 Louise Lukowskis in Bay City during the 1880's - 1910's. Two were born in the mid to late 1880's and the third was a bit older. The 4th appears to be a Louise married to a Lukowski.

As it turns out my grandmother was the daughter of Michael Lukowski and Clara Tykowski. I've found Michael's immigration date and data on my grandmother and siblings but can find nothing on the Tykowski family.
