Gregor Halvorson

I made an error when doing the previous posting....I am in search of Gregor Halvorson, rather than Halvor Halvorson. Gregor was born in Numendahl, Norway on 17, Feb. of 1856. I am sorry for the error. ------------------------------------- I am in seach of information regarding my Great-grand father who went by the name of Gregor Halvorson in Numendahl, Norway. He was born 17, Feb.1847. I do not know what year he came to the United States. He later married a girl from that same area who was named Berget ?Baasket, I believe was her maiden name. Her date of birth was 6, May, 1856.. I believe they came to this country on separate trips, and later married in Dakota territory. Thank you very much for any information that you may find.
