My great grandfather, Omund Olson, the 6th and last child of Sigri Gunnersdatter and Ole Larson was confirmed on August 7, 1881.
Here is the official Odda parish record from Hordaland County, Norway (entry #3) though his first name is misspelled as "Aamund".
A duplicate register was kept so the parish priest and the clerk could compare twice a year to correct mistakes or omissions. Neither the official nor the copy of the parish records were kept together in the event one was destroyed. I haven't always found both parish registers, but on the few occasions I have, they have been helpful to decipher illegible handwriting.
Here is the Odda parish copy of the confirmation record.
