Who is Albert ?

Hi, I am new here. I am finding it very hard to research norwegian names so I have to ask for help. I am looking for the names of my great grandfathers parents. Family history states that he is the second cousin of Professor Carl A. Mellby, born Jan 5 1869 in Oslo Norway. This means that one of his parents is a first cousin of Reverand Ole Andersen Mellby, born Jan 9 1843 in Feiring, Akershus or a cousin of his wife. Ole Mellby's wife is Sigrid Marie Engebretsdatter, born feb 18 1839.
