Thanks very much for the info.. I have copy of Henry's service record; he was stationed at Gibraltar, Bermuda, Halifax Nova Scotia, St Helena and Plymouth. My grandmother was born on Drake's Island in Plymouth Sound - one of the Palmerston Forts. As regards John's birthplace, North Wheatley is listed in the Mormon's online 1881 census where he is shown as a licensed victualler and farmer of 36 acres. I've come across North Wheatley, Beckingham, Walkeringham, Gringley on the Hill, Saundby and Gainsborough in connection with the Cockings so I assume they are all branches of the same family.
