Scoop, thankyou for looking into this for me.
Firstly my apologies for my typo which I cannot explain, except to play the old age card! We are looking for Albert.
The Medal is the Victory Medal which is engraved Albert Henry Markham and has the number 18354. This number (from his Army record) he received when he transferred from the Royal Artillery into the Royal Berks shortly after enlisting. His original R.A. number being 87131.
His next of kin are listed as mother Emma and brother George William, both living in Peterborough. From this I traced the family and Albert's birth was registered in Oxford 1st qtr 1888. This birth year is recorded in subsequent census as is mother Emma's address in 1911, confirmed on Albert's enlistment papers. Unfortunately the Army did not record a date of birth, but Albert is shown to be 24 yrs old, he was in fact 27 yrs old.
Albert's bapt. record gives a dob 25 Jan 1888, the same as that shown by grandarog, The death reg. in Devon 1965 also shows a correct birth year of 1888.
Winifred Daisy Teed's Birth reg is in 2nd qtr 1894, near Exeter Devon. 1911 census gives a birth year of "about 1893" so fairly consistent. Thereafter as you rightly note it gets very wobbly. I cannot yet confirm an actual date.
It seems then that between 1935/9 they removed to Devon and both died there, Albert in 1965, Winifred 1989. I haven't found any children either.
