Gaasemyr/Sandene/Sande

I hope this is the correct way to do this. I am looking for another branch of the family. Here is what I think know. Gabriel Nielsen Gassenyr, father Niel; married Magnild Thorsdatter, father Thor; they had a child Mons Gabrielsen Gassemyr born in Gaasmyr, Gloppen Norway on 12/27/1820 who died in 1901 in Sandene, Norway, married Ragnhilde Nilsdatter Sandene on 12/11/1848; I would like information on Babriel Nielsen Gassemyr and family. Thanks so much in advance.
