Leslie I would try a Dutch list to see if you can get a different spelling. Tried different spellings and could not find him on a passenger list. I found him and his family in St. Louis in 1910. Elizabeth and family in 1920 & 1930. Her sister Mary Koch is living with her Jacob was naturalized. His papers should be in St. Louis, also a death certificate. He said he came in 1880. Elizabeth came in 1881. On the 1920 census she said she was naturalized. If you do not already have this information I can give you more from the census. They were probably married in St. Louis. All children were born in MO. I found one reseacher. Will give his name direct to you if you want. He said the name was Morsingkopf. I also tried that spelling. Carlene
