All 3 of these names have been used in the States since my adopted father's dad came to the US when he was 17. His 1 brother was in CA and another in ND. My parents took Grandpa to see the one in CA, but no one knew where the rest of the family was. It is believed that a sister remained in Norway.
Our Jhanson(sounds as J-an-son) name was supposed to be Johnson(Johan's son). Any input?
