I am trying to trace the daughter of Dr George Roger Parker and her descendents. Mary Audrey Parker (b.1889) married Dr William Rail and moved to Rhodesia from Lancaster in the early 1900's. I have a letter from her to my mother dated 31 Aug 1969 Grove Road Greendale Rhodesia. I also have some photos from a trip back to England around 1919-20 where one of their sons was born. Mary Audrey would have been my Great Aunt.If anyone has any information on any of her children or grandchildren I would be grateful.
