Hi Deadants
Possible contenders :
Harry born in 1889 Eng,
Hubert born in 1891 Eng - Discount him now as on the Ellis Island records he had fair hair and blue eyes. The enclosed chap looks to have dark brown eyes.
Edwin born 1904
Leslie born 1905.
Earlier men in the family where :
Harry born in 1866
and James born 1868 in London,
Their father born in 1835 a Clerk, and another son but its not him.
Some of the photos were plain like this one and some had Amy's Fathers name on, taken in Wandsworth. Believe none of the photos were originally in colour.
Yes, think your right about being pre 1970

and you have done a very good job on the photo.
Thanks a lot for your help.
