An ancestor of mine joined the 2nd East Lancashire Field Ambulance Brigade in November 1914, he served with them up to August 1916 when he transferred to the Royal Flying Corp, starting off in the rank of 2/am and then from October 1917 as 1/am, finally being promoted to ?PL mechanic in 1918. Has anyone else come across a man who started out in the army and then ended up in the RFC and later the RAF?
