Neill Gilhooley was born in Edinburgh. He worked overseas as a project engineer in the oil and gas industries and now lives in Nottingham with his wife and two children. His interest in the 9th Royal Scots was aroused by his grandmother's stories of her father's service in the battalion, including a vivid memory of him coming home on leave and running the naked flame of a candle up the pleats of his kilt to rid it of lice and their eggs. He has compiled a half million word index of the personnel of the battalion.
