This one has got me puzzled (not hard I know

)
PA27132 lists Herbert Firth 2/6th Bn, born Leeds 15.02.1887, taken Gincourt presumably Jeancourt 21.03.1918, held at Skalmiersch�tz. He has no index card, the reference to him is on the index card of 50399 Harry Firth, 16th Bn, born Oldham 26.07.1889, 20 Princess St Oldham, taken 21.03.1918 St Quentin. There are two Herbert Firths in the MICs: 31315 Manchesters also 129296 MGC, and 303052 Herbert O. Is it a mis-transcription or are they two different people. Princess St Oldham is in Lees.
can anyone shed any light please
