Edward Tew is my grandfather, who in 1905 in Minn was 27, making his date of birth 1878. My mother told me that her mother told her that he came here when he was 20, making the year around 1898. So somewhere between 1898 - 1905, he came here from Norway. He told my family that his last name was Tuuve, but had to change it to Tew since Americans found it difficult.
Any tip in the right direction will help.
