Hello there, I am searching for the first wife (I believe she was French) of my ancestor William Ruskin Allen (b. 1895 in Berkshire, England). The only lead I have is the summary of a letter written by William Allen's father John, to William's wife, when William was taken prisoner in World War 1. The letter was donated to the Imperial War Museum and they then lost it (only the summary remains, which does not name William's wife).
William lived in France (mostly Paris) between 1912 and 1917, so if the woman he married was French, it would be during that time. He did not marry in England. After being repatriated at the end of the war, William returned to England, and later married a woman in Ghana. His children from that marriage know nothing about a first wife and deny her existence.
Any help would be so appreciated. I have been searching for her for many years.
Here is the link to the letter summary:
