Would you please advise the exact location of Swalmland, the monument, castle, etc. My daughters would be very interested. I am looking for my G,G,G, Grandfather, Anthony Knouff's father. Anthony was listed in South Woodbury Township in the 1840 and 1850 census for Bedford County Penn. He was born in Maryland in 1799. I will search my files for your Ralph Frederick and advise.
