Hi again and apologies for causing an obstruction.
As mentioned before I grew up 4 doors away from the Rabinowitz family in Krugersdorp,at 113 Commissioner Street.
I know that there were 2 daughters a little older than I was.
Sally was about 5 years older and Biddy was 2-3 years older than I was. Two sisters so completely different looking.
Sally was a red head and freckled , and Biddy was a brunette and more tanned.
I no longer live there but still know a few people who may be able to assist.
My parents were of a similar age group to Archie and his wife.
Please let me know if you would like me to help.
Good luck with your search.
