Thore Thorsen, searching for my great-uncle

Hi I've been researching my Dad's family since right after he passed away in 2012 and have been stuck on my Great-uncle who I cannot find a thing about after he and his sister came to the US. (My Grandpa came too, but he came with another family member because my G-Grandparents drown on their boat, the Maria, during a storm, so my Grandfather went to live with his Dad's sister and my g-aunt and g-uncle came over with his Mom's brother). My grandfather's name was Knud Thorsen and the one I'm looking for was Thore Thorsen. Following is all the info I can find on him: Thore Thorsen Birth: Abt. 1865 - Stavanger, Rogaland, Norway Death: Not Available - Mother: Dorthea Larsdatter Hertervig Father Knud Thorson Thore Thorsen was born in Stavanger, Rogaland, Norway on Abt. 1865 to Knud Thorson and Dorthea Larsdatter Hertervig. Jorine his sister, arrived in New York on 31 Oct 1884 aboard the S. S. State of Indiana. Jorine was born 17 May 1867 and baptized at St. Petri church on 23 Jun 1867, S/S Indiana, American Line 1873 March 25, launched 1873 Oct. 27, maiden voyage Philadelphia - Queenstown - Liverpool Sex: Male Birth Date 29 Sep 1865 Father: Knud Thorsen Mother: Dorthe Larsdatter Event Type: Christening Event Date: 19 Nov 1865 Event Place: Stavanger, Rogaland, Norway After the death of Knud and Dorothea, the kids were sent to live with different people. Thore and Jorine were cent to live with Dorothea's Sister, Sissel Larsdatter Hettervik in 1875, and Lauritz was sent to live with his Father's Sister, Astrid (or Astri) Thorsdatter in 1875. 1. Thore, born 1865, lived with aunt Sissel Larsdatter Ommundsen in 1875, in Stavanger. 2. Jorine Cecilie, born 1867 lived with aunt Sissel Larsdatter Ommundsen in 1875, in Stavanger. Jorine Thorson came to New York, New York (Castle Garden) USA on the ship State of Indiana. Arrival Date: 31 Oct 1884 at 17 years old from Glasgow, Scotland/Larne, Ireland 3. Lauritz, born 1869, lived with aunt Astrid Thorsdatter in 1875, in Årdal in Ryfylke. That's all I have, My Dad said his Father and siblings all came to the USA. but I lose track of Thore after he came here. I recently got ahold of a letter written from Jorine to Lena, but didn't see any mention of Thore. Can anyone help? (I tried to put the letter in here, but it's not letting me add it for some reason) Also I'm trying to find where Jorine is buried but even with using "Find a Grave" I can't locate it, so if anyone can help with that, it'd be much appreciated. Thank you
