Thank you Jon and Rosie. I appreciate your help.
Rosie, I do not have a date of birth for George, just that his death record says was aged 79 when he drowned in May, 1909. He had been in New Zealand for 45 years.
I now wonder if he could be the George in the 1841 census as some of the names in that family are the same as those of his own children, Elizabeth, George and Henry.
Jon, I am intrigued by your mention of the George Kent who went to sea as a boy in 1841, as “my” George is supposed to have left home at a very young age.
