My g grandfather, Lars "Lawrence" Engberg, was born in Sundsvall in 1838. One of his brothers was Johan "John" Engberg, born in Sundsvall in 1849. According to the 1890 Census in Sweden, Johan was married to Lovisa Katarina Dubeau. They had 5 children: Johan Ferdinand, Emil Bernhard, Gerda Elisabet, Helmer Georg, and Oskar Emanuel. I hope to find one of their descendants. Where do you live in Sweden?
