Seeking info on great grandfather Goodman

I’m looking for information on my late great grandfather, Moss Goodman, my grandmother’s father.

He was born in 1859 in Whitechapel, London, and died on 20 October 1919 at the age of 59 to 60. Moss was the biological son of  Barnett Goodman and Elizabeth Cohen, and after being orphaned at the age of two, was adopted by Aaron Barnett and Priscilla Barnett. The Barnetts emigrated to South Africa. My great grandfather returned to England, year unknown.

Please assist with any information you may have at davipat70@yahoo.com
