Have , at last, solved the mystery of Jimmy, the soldier in the photo.
He was born in 1920 to Marion Fawcwtt, nee Campbell, widowed. Father was James Muirhead, also a widow and who lived a few doors away in the same street.
So far, it appears that Jimmy died in Glasgow in 1978, he was using the surname Fawcett. Just waiting on death certificate to confirm that this is the same man.
