I am also looking for relatives with the last name of Bogacki. These Bogackis are from Mikluszowice, Poland. The oldest we know of is Frank Bogacki, married to Mary Serafin. The only child we know of was a son, Joseph, who was born in 1882 in Poland. He was married to Barbara Sadulska. Then we have Henry (my father-in-law) who was born in Chicago, IL. Any information is greatly appreciated.
