Just found your thread and thought you might be a decendant of Robert (Bob) and Lillie Fernihough who were living in Pretoria in the 1920's. I know of three children; Joe, Lillie and Nell. Bob and Lillie kept the Post Office at Pretoria North and farmed.
Bob (b.c1880) had three brothers, James Henry (Henry), Thomas and my grandfather Arthur, and a sister Polly.
If these are your relatives please let me know as I have letters and photographs.
