The Ministry of Defence is trying to trace any living relatives of a young soldier who may have come from Newport Pagnell.
He died during the First World War and his remains have subsequently been discovered.
When the remains of British Service personnel are discovered on historic battlefields, the MOD attempts to identify any living relatives so that they can be involved in the subsequent re-interment and memorial service.
An officer of the Oxford & Buckinghamshire Light Infantry, the man died on May 3, 1917 near Beaurains in northern France.
The MOD said the remains discovered belong to one of four officers, two of which are from Buckinghamshire, who died on that day and hope to discover which one by finding surviving relatives who might be able to provide a DNA sample.
The officer could be 2nd Lieutenant Charles Croke Harper of 3rd Battalion attached to the 5th Battalion Oxford & Buckinghamshire Light Infantry.
He was the son of Revd E J and Frances Wetherall Harper of Broughton Rectory, Newport Pagnell.
Born in 1880, he had two brothers and four sisters.
