Hi Elrene, I got your private message and will respond later. I've had a need for some time to put together the information on the South African family ... time being an issue!
For now I'll summarise some information that might help other researchers who come here.
Henry George BROWN
1856–1916
Birth 16 APR 1856 • Isleworth, Middlesex, England
Death 31 DEC 1916 • Kuruman, North Cape, South Africa
Henry was the first son of William George BROWN and Jane Clissold DANIELL of Frome in Somerset. Online searches will reveal this in his wedding announcement. William and Jane went to London between 1853 and 1856, returning to Frome to rejoin the family building firm. WGBs father was William BROWN (1795-1861) who was born in Somerton, Somerset. The BROWN name goes back to the beginning of church records (abt 1700) in Somerton. Wives families also lived around that area. The names PEDDLE, INDOE, FOSTER and more crop up regularly among family marriages.
We do not know why William BROWN moved to Frome as a young carpenter. He first appears there when he first married in 1815. He found work as a builder, and eventually included three sons in the building firm, including William George BROWN, the father of Henry George BROWN. They built many significant places around Frome, especially many churches. WGB focused mainly on being an architect, his brother Frederick seems to have run the building side. I do not know what Henry did, I suspect he had a role in assisting with the running of the business, because in 1879 he accepted a job as Clerk of Public Works in Grahamstown, South Africa. This role is very much a Project Manager role. He arrived in 1880.
Family tree information is on Ancestry. I did a quick search today to see if your branch had been entered by anyone else, as I do not have it. I found a tree by someone in the USA that shows your branch down to your father, but his Henry George was described as coming from Yorkshire, so I suspect they've gone astray somewhere in their research! It wouldn't be the first time I've found significant issues, but the message for you is to check that you and I are talking about the same people! I've written to a proven South African descendent to see if we can get more information on your branch.
I'll contact you again when I've put together a more detailed history.
