Searching for information about my wife’s brothers. The family name was Zeeman and they lived in Northern Rhodesia (which is now named Zambia) in Africa. The children were named Yvonne Zeeman (my wife), Yolanda Zeeman (sister), Walter Zeeman, and Leslie Zeeman. The brothers Walter and Leslie were born in the 1950's which would make them in their 50's now.
The brothers were both adopted in the 1960's by a family surnamed French. Their adopted parents were Douglas French and Olive Avis French. Olive's maiden name was Olive Leahy or Olive Laye? The brothers were renamed Michael Walter French and Robert (Leslie?) French. Douglas French was associated with the Nkana mine at Kitwe, Zambia. We have heard that this family later moved to Australia but cannot confirm this.
