My tree is public under Brown/Bradbear/Hiscox/Parker. This is what I have
William Arthur Rail born Sydney 1886 N.S.W. Married Mary Audrey Parker from Lancaster and moved to Rhodesia. Children as per letter of 1969
James Rail b. 1914 (55) living in Capetown,
Peter Rail b. 1915 (54) living in Casino NSW is a Consultant physcian,
Margaret b. 1917 (52)living in Salibury Rhodesia
Roger b 1923 (46)and "very sick with a thrombosis in an artery in the brain living in Yumba mountains"
I think Roger is the only one not born in Africa
They would all be pretty old by now though.
I will take a look and see if I can find the trees you mention
