Hi Elaine - yes I live in New Zealand. My father's name was Arthur William Herbert. The missing Herbert Gally was born abt. 1855 in Kensington London - last census was 1871- apprentice to Printer. No trace of him since then. His parents my gggrandparents were John Cockburn and Sophy (Sophie)nee Cox Gally. Their children were Louisa, Herbert (the missing son), John (died aged abt 5 or 6, Arthur (my gggrandfather),George, Ellen (Nellie),Amy and Alice.
Just had a thought - maybe the missing 'e'the family talked about was actually added. Maybe Herbert decided to change the spelling and added the 'e'. Lovely talking to you. Fran
