I found Signes parents and siblings at Kjellevål farm in 1900.
Her father goes by the name Hans Andersen born 1841, and mother of course as before Ragnhild Monsdatter. Their children are Rasmus Olai b. 1875, temperarily working in Mundheim, Hardanger. Dorthea Helene b. 1885, works at a farm. Gjertine Andrin, b.1887, Andreas, b.1890 and Harald, b.30.7.1900. Signe is listed as well, but only with the firstname Sygni, and she has been overlined from the record, probably because she had allready left for America.??
Since I now know her fathers lastname was Andersen, I will check were he lived in 1865.
