This index has pre-1907 vital records. It does not have all records, as registration was not required prior to 1907.
This page at www.findagrave.com
lists an Elmer Fay Anderson, who may be Carl's son. It also lists a Maud Anderson, wife of Carl who died in 1911, so perhaps she died in childbirth with the youngest son http://www.findagrave.com/cgi-bin/fg.cgi?page=gsr&GSiman...
