My great grandfather was Charles Fredrick and I have a picture of him on my landing wall. I also have a picture of his wife Emily. They moved from Elephant & Castle to Ruislip I think. They had a son called Bert (Charles Bertram Jarman) my grandfather who moved out of London and started a manufacturing firm in Buckingham.
They didn't go to Australia, although Charles Fredrick did go to India with the Royal Hussars.
