I have having quite some trouble finding information for John Henry Gieske's father Christian Gieske.
John Henry Gieske was born Jun 6 1840 in Hesse, Germany and passed away Nov 14 1903 in St Paul, Ramsey County, Minnesota. I found an old passenger record that lists Christian's surname as Gierke and also Giseke. Christian was also born in Hesse, Germany 1813
Christian came on ship named Caroline with Ann and was born in 1803. I'm not sure if it's his wife or if it's his sister I haven't been able to find any records for Ann
