Herman begat Christian and other sons and daughters.
Christian begat Jacob and other sons and daughters.
Jacob begat Jacob (Jack) and Robert.
Robert begat Daniel, Klemet, Katy, Rolf, Peter, Solveig, Christian, Karen, Ruth, and Erik.
Rolf begat Daniel, David, Paul, John, Mark, Stephen, Christian, Andrew, James, Mary, Samuel, and Peter.
The children of Rolf who have posted on Luther Quest are: David, John, Mark, Stephen, Christian, Andrew, and James. I think.
