I Am Looking for Past Connections to Gustav Kreegher Kruger and Wilhelmina Minnie Schwanke Kreegher Who Arrived IN New Zealand Aboard the Ship Rakaia ...

To the best of my knowledge Gustav was born about 1853 in Prussia, Germany. Other than that and when they arrived in New Zealand with their son and daughter not much else before this is known. Would be interested to know more if anyone has any information that might help.
