My maiden name was Mulac. My Great Great Grandfather was Rudolph Mulac Sr. He married Filomena (Simek). They had 7 sons Rudolph Jr,Louis,Robert,George James,Edward & Ervin and one Daughter Mary (Tresselt). They lived in the Chicago area. Came from Bohemia I believe. The information I have on Rudolph Sr. is that he was born in 1866 and died in 1948.
