Jens Riisberg family

In 1801 in Gjerspen Talemark is the family of Jens Riisberg. His wife is Anne Karine Haagensdatter and his son is Peder. Jens also used the name Christensen and he is listed on Peder's christening record as Jens Christensen Riisberg. Peder's christening was on 25 May 1800 and the image is here http://www.arkivverket.no/URN:kb_read?show=17&uid=535628&urnread_imagesize=gigant&hode=nei&ls=1&lc=x%259CK%25B42%25B2%25AA.%25B62%25B4R%25CAT%25B2.%25B62%25B1R2%25B7%25B00%25061%2581B%25C5J%25D6%2599V%2586%25E6%25D6%25B5%2500%25C0q%2509%25C4 I see other names on this document. One is Lars Riisberg. I think Lars is Jens' brother. Does this record indicate relationships? Who are the others? a I find indexes to other children of this couple on familysearch.org Karin baptized on 26 May 1806 and Ole baptized on 11 Dec 1808 I also see Anne Kirstine Jensdtr christened on 12 May 1816 and Anne Dorthe Jensdtr christened on 3 Mar 1822. Their parents are Jens Christensen and Anne Karine Haagensdtr. That is a huge gap for the children which makes me think there must be other children. Or perhaps another couple with the exact same names. This seems unlikely in such a small town. Here is the record of daughter Karin. http://www.arkivverket.no/URN:kb_read?uid=537223&urnread_imagesize=gigant&show=30#toppen I have the same questions about the other people on this record Here is the record of son Ole http://www.arkivverket.no/URN:kb_read?uid=537890&urnread_imagesize=gigant&show=35#toppen Thank you Leslie Vaughn
