Gary,
Thanks for checking! It's possible there is a link but it doesn't look probable. My great-grandfather, Charles Johnson was born is Smaland Sweden August 14, 1829 in Killard Parish. His Swedish name was Carl Johannesson. He immigrated to Austin, Texas in 1854 and married German immigrant Amelia Loeschmann about 1857. He was a stonemason and rock contractor.
Thanks again for looking,
Troy Johnson
