have done some research in archives of Archdiocese of Chicago....
have found many Jakubowskis in church records, very common name, also
Stanislaus (Stanislav, etc) is very common first name
have copies of baptism, death and marriage records for about
10 different Jakubowski families, circa 1890-1913
email me with first names and dates and I'll
see if I have anything that matches!!
