His mother (Maren Weiby) is listed on the pioneer company roster with "two children." Perpetual Emigrating Fund records confirm that Hans and his sister Birthe were the children referred to. They had crossed the Atlantic on the ship Emerald Isle (their surname is spelled "Veiby" on the passenger list.)
Hans' death date was found in a personal, online family history record (such as Family Tree, Ancestry, or My Heritage), without any accompanying documentation. Further research is needed to verify accuracy.
