Here is the baptism record for Omer O Jordal (#1), Martha Svenia Jordal (#14) and LaVern Amos Jordal (#10), grandson, granddaughter and great grandson of Sigri Gunnersdatter and Ole Larson.
Witnesses (below) for Omer included his aunt, Guro Haldorsdatter Mæland. Another witness, Samson Mæland is most likely related to Ingeborg as well but I have yet to find the connection.
Witnesses for Martha do not appear to include any blood relations.
Witnesses for LaVern included his father, Lars and uncle Simon Jordal.
The baptism record indicates Omer was born October 18, 1902, though this may be an error. The social security death index states he was born October 19, 1902. Omer was baptized January 18, 1903 and was the fifth child born to Ingeborg (Haldorsdatter Mæland) and Omund Jordal.
Martha Svenia Jordal was the sixth child born to Anna (Larson Jossendal) and Gunder Jordal. She was born September 7, 1903 and baptized October 11, 1903.
LaVern Amos Jordal was the first child born to Elizabeth (Brown) and Ole L Jordal. He was born February 27, 1904 and baptized April 17, 1904. LaVern was the grandson of Isabelle Cordelia (Halvorson) and Lars Jordal.
