Many thanks David for this information and being able to discount these Haycrofts. I have found that Sydney's mother, Lizzie, died in B A, Argentina in December 1864 in childbirth and also his sister Clara died in June 1865 age 10yrs.I have not found Sidney in Argentina or any where else for that matter. Sidney was born in Plymouth, Devon in 1856. I am trying to find out when he came to NZ and also when he left.I will keep searching - something is bound to turn up. Thanks again for your assistance.
