Else Marie / Erik Eriksen

Hey, So a bit of an odd occurrence. Perhaps you all have an idea of what's going on here. Are these both twins or the same person, or what happened? Else Marie Eriksen was born on 6 May 1923 in Modum, Buskerud, Norway https://www.familysearch.org/ark:/61903/1:1:683J-VJ4F At Ole Evensen Marigaardseie's Death Notice in 1924, Else Marie was listed, but no Erik Eriksen. https://www.nb.no/items/9dfb3d2ebcf241f0e09a4c2f2a94c165?page=3&searchText=%22Else%20Marie%22 Ole Evensen, Anne Marie Evensen, Erika (Ole's daughter), and Oskar Eriksen's gravestone show Erik Eriksen as well with the date 6 May 1923 to 03 Mar 1943, same as listed here: https://www.digitalarkivet.no/en/view/433/pc00000004308309 Did Else Marie die? Erik clearly died according to the record and gravestone. But why was he not listed on Ole's death notice? The same birthday, plus that fact, makes me think that Else Marie is Erik, but I have no idea. Else Marie was also not listed on her father Oskar Eriksen's death notice in 1971, only her brother Arne. https://www.nb.no/items/b60d4ea3668784ca1e8e225a13f65b2b?page=9&searchText=%22Oskar%20Eriksen%22 https://www.nb.no/items/5097bdae7b5da824e0a10e1f04bfb418?page=5&searchText=%22Oskar%20Eriksen%22 [View image]
