My granduncle Jeremiah (Jerry) Neville lived for 26 years in Chicago having spent a number of years in Canada after he left Ireland in 1924. He married Pauline Mackin (or Corcoran - she may have been a widow) about 1940. Pauline was from Louisville, Kentucky. They had no family. I've searched the Cook County records & can't find a trace of the marriage record. Is there another source I could try?
