I am searching for a man who I believe to be named Chris or Christo who would have met and fallen in love with my Nan Patricia ‘Susan’ Lee, known as Sue. She lived in Kwaggersrand -South Africa (please see image attached of mums address) in 77/78 and worked at Iscor in Pretoria as a crane driver. I will attach further images in the comments. I know it’s a long shot but with not much to go off it’s becoming a struggle. This man is birth father to my auntie Lisa, who we believe he wrote letters to and was sent photos when she was a baby. Pic below we believe this may be Chris or could be someone who knows him. Thanks

She moved back to England U.K. whilst pregnant with Lisa and raised her as my grandads along with her 4 older siblings.
