By any chance are you related to Robert Allan? I understand he was involved in government in Rhodesia, and he died in 1962. He was originally from Scotland, and hadtwo brothers, Sam and John, and a sister, Maggie. Sam was my Grandfather, and moved to Toronto, Canada permanently after WWI. Robert, Sam and John grew up in Motherwell, Scotland. These Allans were origionally from Wishaw.
I also understand Robert Allan was also awarded an OBE during his lifetime.
We've long since lost contact with that branch of the family, and I'd like to put the pieces back together! If you can help, I'd appreciate it.
