Deceased estates notices in the South Africa Government Gazette 7 July 2023 no 48890 part 1 pp 165 and 188 reveal that Keith John DON-WAUCHOPE, resident in Ladysmith, has died. These notices relate to filing of administration accounts inviting any objections before the estate is distributed. Unfortunately I can't find any earlier notice which would give the date of death. However the probate notice is numbered 7387/2022 so I assume the probate procedure was started in 2022 which indicates the death may have been 2021/2022. The notice also gives the name of his surviving spouse as Erica Louise Don-Wauchope - he is shown as unm in DPB online.
He was the son of Malcolm John DON-WAUCHOPE (1939-2019) son of Sir Patrick George Don-Wauchope, 10th Baronet (1898-1989)(NS 1667) and (m 1936, div 1947) Ismay Lilian Ursula HODGES. He was a nephew of the present Baronet
