I now know that Edgar had married Ethel (Louisa) Worby by 1904 and transfered to the Indian Army where he was a Staff Sergant in the Supply & Transport Corp. They were married in Rawal Pindi. Edgar died in norther India in 1920 of pnuemonia. In 1930 Louisa married Audley Lett and returned to England some time later. Of Edgar & Louisa's 4 children the Oldest Donald, my Grandfather, went on to serve in the Royal Engineers from 1929 to 1954 serving in North Africa and at the end of WW2 in the Bomb Disposal Units around the UK. Edgar Robert was killed 1943, He was a Military Policeman and is buried in Ramsgate. Dorothy, the only girl died in Kent in the 80's as did Louisa. We believe that Louisa would have been around 102 yrs of age. And as for Jack, I have found nothing concerning him or any trace of him at all.
If anyone sees this and recognizes any details, please let me know.
