Hi, I know I am 11 years late in responding. My great-great grandfather, in which I believe his name is John Jakubowski came from Russian Poland. He was married to Teofilia "Tillie" Warakomski. I know they had multiple children, from the census, but my line is Walter Jakubowski. Walter married Estelle "Stella" Gorlaczyk. Some time during the 1900s, my line of the Jakubowski's changed their name to Jacobs, to be more "American" according to Walter. Do you have any information at all on these Jakubowskis/Jacobs??
Side note, I know for a fact that Walter's sibling, Joseph Paul married Marie Studentovicz and had three children. Looks like there are other names, too, but I don't get my hopes up in adding them, because they may not be relatives. Jakubowski is such a HUGE name in Chicago.
Thanks so much,
