Carole Fife has provided the following:
John was born in Bedlington in 1888, the eldest son of William and Alice Clark. In 1901 the family were living at Ridge Terrace, Bedlington, and William was working on a farm with the job title of 'Farmer's Son'. In 1911 Alice had died and the family were living at Burdon Terrace, and John had joined his father in working on the farm. Later the family moved to Netherton Moor. What is unusual in John's story is that he joined a Scottish Regiment and that he enlisted in Dunkeld near Perth. John's younger brother Robert was a grocer's assistant who very likely knew George Price Chilton who worked in a grocer's shop in Bedlington, and also enlisted in Dunkeld, so it looks as if John and George travelled together to Scotland to enlist. John enlisted originally as Private 6025 in the Scottish Horse but his regimental number was changed. (George joined the R.A.M.C. Unit attached to the Scottish Horse) John was nearly 30 when he died, but his legatee was his sister Isabella, which would indicate that he wasn't married.
He is remembered at Bedlington on B15.02, B15.03, B15.09, B15.20 and B15.26 page 72
