Jensen's family from Denmark.He was born May 8, 1882 in Denmark and came to America in 1902/1903.He had three siblings, all born in Denmark.Two of which also came to America, Peter C. Jensen, born August 27, 1883, who came to America the same time as James and Marie J. (Jensen) Pinchard, born September 5, 1894 who came to America in approximately 1913.James parents names are possibly Jens & Dinah Marie.James settled in Nebraska and Peter and Marie both settled in Wisconsin.I would appreciate any information relating to James, his parents or any of his siblings.
