Trying to connect two possible brothers

Hey everyone! I have a suspicion that two individuals may be brothers but I'm having a hard time finding good records on Digital Arkivit for Vinger during 1827-1835. Perhaps someone might have a few minutes to lend me? What I'm looking for is Johannes Johannesen and Evan (or Eivind) Johannesen. I believe this is Johannes on the 1865 census: https://www.digitalarkivet.no/en/census/person/pf01038039001396 Johannes Johannesen b 31 August 1835, Fagernesbakken, Fagernes, Vinger, Hedmark Even Johannesen b 8 August 1827, Norway Based on DNA tests I have a reason to suspect these two may have been brothers. Johannes's daughter Olia emigrated to the US, and Evan also emigrated to the US. Even came to Minnesota by at least 1855 and served in the Civil War but it's unknown right now where he came from. Thanks for any help you might be able to offer! I've checked the ministerialboker for Vinger but the dates are all over. (Found an 1834 birth registered in 1835...) The kirkeboker are also not showing me anything unless I'm overlooking or looking in the wrong place. Here's my current research page for Even/Eivind: https://www.blyfamily.com/webtrees/individual.php?pid=I294&ged=Bly%20Family Thanks! James
