I'm looking for information about the family of Carl Gustaf Carlson. They immigrated from Sweden with their destination listed as Round Rock, Texas, on August 8, 1890. The family included his wife Anna Charlotta; sons Frans Oscar, Gustaf Theodore, and John August Jelmar Carlson. I haven't found any of them in either the 1890 or 1900 Census.
So far I haven't been able to find any records of the family having arrived in Round Rock. In some genealogical work Carl Gustaf Carlson and Frans Oscar Carlson are both listed as having died in Texas in June 1900. No details were given.
Gustaf Theodore Carlson next appears in 1911 Georgetown when he marries Lillian Sophia Swedhin. So far I haven't found him in the 1910 Census. In the 1910 Census, Anna Charlotta Carlson and her son John August Jelmar Carlson appear in Kandiyohi, Minnesota.
I'm looking for any information on the Carlson family in Round Rock and Williamson County between 1890 and 1910. I'm especially curious about any information about accidents or otherwise in June 1900 that might have accounted for the death of Carl and his son Frans.
Carl Gustaf Carlson is my grandfather and I'm trying to solve a few mysteries in the family genealogy. Any help is deeply deeply appreciated. At the moment, I've hit a brick wall in my work.
