CAMERON family:
John Cameron and Janet Cameron (Nee McGregor) emigrated to New Zealand with their children; John, Angus, Charles, Duncan, Allan, Ann, Archibald, Dugald and Marjory. They moved to Kaiwarawara, which must be near Wellington. Later they moved to the Turakina Area, near Wanganui. John died in 1881, allegedly aged 100. If this is true he must have lied about his age on the passenger list. (Latest research points to his age at death as 90 years old) Apparently this was not unheard of for prospective migrants to lie about their age. They must have been good Christians judging from a memorial found inside the church in Turakina, "To the glory of God and in the memory of John and Jeanet Cameron our great grandparents. The first service to be held in the parish held outside their residence 15 December 1852."
…. The Cameron Clan New Zealand website…. has good information on the Camerons including a shipboard diary written by a passenger aboard the Blenheim.
