According to Ana Kendall - The 1851 census states that Henry Kendall (34 years) was living in Pavenham, Bedfordshire, with his wife Harriet (25) and their son Henry (age 1). They were farmers with 100 acres. It also states that Henry and Harriet were born in Odell, Bedfordshire.
His death certificate states that he lived in the Commonwealth for 38 years; 13 years in, New South Wales, and 25 years in Victoria, toria. The certificate further states he was married to Harriet and had two sons; Henry 39 and Thomas 37.
This would give his arrival date in Australia about 1851-53
