Signe Thorkildsen, Lars Torkildsen, Jacobine Dahl

Scotty didnt beam them over!!!!!!! - My G-Grandmother is Signe Gurine Torkildsen (married a Christiansen) Born 1879 in Christiana, Norway......Confirmation 1896 Brooklyn NY - Signe's mom, Jacobine Caroline Dahl Born 1834 Larvik, Norway, dies 1899 Brooklyn NY - Signe's dad, Lars Gunerius Torkildsen born 1834 Akershus, Oslo Norway.......MYSTERY! Last know to physically exist is on another daughters confirmation, 1883, Akershus Norway. I cant find how the women got from Norway to the US, therefore, I cant find out if Lars died prior to them sailing, during, or in the US. My sleuthing has them sailing between 1883 and 1896. Plase help! Tammy
