Forgot to mention that Harry Adams came over with his sister as well, Sarah, she married a John James (Jack) Arnold. Hope that helps you narrow things down.
From what I know, these people are the staunch Salvation Army people, Harry was described as a Corps. Sergeant Major.
Have just found some more: Sarah Arnold died in 1961, aged 88, might help find her birthdate. John James Arnold died in 1944 at the age of 73.
Thanks.
