Evelina, or Evelyn as I knew her only had a daughter, Joan Nathan killed in the WW 2 Blitz.
She died in 1965 in Harrogate, Yorkshire.
"Lewis", actually Louis Charles Edward, was my father. I was one of five siblings, three boys and two girls. Died in Aguilas, Spain.
Percy Randolph died a bachelor in Welwyn, Hertfordshire.
I never met my grandfather Edward and did not know he had a brother Julius, until recently.
You must be related to Julius. Have you much information on his German family?
