Hello,
Jon Leifur was my great grandfather. His eldest daughter, Victoria, married another Icelander, Gunlauger Trigvie Johnson in North Dakota in 1919 (approximately.) My father was their youngest son, Robert Delano Johnson, born in 1934 in Kensal, ND. He remembers attending a 50th anniversary party for John Leifur and Finnbjorg Finnsdottir in 1940. in Minneapolis.
My husband and I hope to take two trips this summer - one to ND and one to Iceland. My grandfather, Gunlauger, had a younger brother who was left in Iceland as an infant when they immigrated to North America in 1893. This was the same year that the John Leifur, his wife and three children immigrated.
We'd love to exchange information!
