Skjervøy Troms Marriage

On the digital image of marriage records of Skjervøy at http://www.arkivverket.no/URN:kb_read?idx_kildeid=9729&uid=ny&idx_side=-230 The marriage of Iver Olson Riisberg dated July 10 1814 is listed midway down the right hand side of the page. Could some kind soul provide a translation and perhaps an explanation.. It appears the bride is Gunild Barbolsdatter There are other names on this record. Are they parents or witnesses? Is Riisberg the name of a farm. Based on this entry would it be safe to say that Iver's father's given name was Ole. what about Gunild. I show from other sources that she was Gunhild Olesdatter. What is the Barbo in her name mean? Thanks so much
