Have now found him and family on the 1911 Census residing with the 1st Battalion RIF in St Lucia Barracks, Bordon, Hampshire.
He is listed as Alexander Robson, Sergeant, age 30, born in Newcastle, Northumberland. His wife and two daughters (Charles the grandson was born after 1911) appear on a later page amongst the other wives and children.
Firstly, Cumbrianangel’s born in Kent appears to be a load of malarky.
Secondly, he was known in the RIF as Alexander (perhaps he was commonly called that at home to differentiate him from his father). We only ever look at the one document on the CWGC site – the one Dave has posted an extract from. But in this case there are four others and you can see the transition of the understanding of his true name from A. to C.A. to the Charles A. B. that appears on the headstone. The fourth document deals with the epitaph “Rest in Peace Our Dear One” and this was obviously supplied by Alice (his wife) rather than his father. So has Alice or a CWGC clerk led us up the garden path by not getting his father’s name correct, after all, as Jo originally said, “he does not seem to have existed” and as far as I am aware the only source of his name as Charles Alexander Burleigh, exactly the same as his son's, is the CWGC record.
Then we come to DoB – if we accept he is the Second Lt on Dave’s list, his DoB was 1 November 1879 (or is it 1878?) His age of 30 on the 1911 Census makes him born between 1 April 1880 & 2 April 1881, the CWGC age at death of 36 makes him born between 9 November 1880 and 8 November 1881. One could construe this as meaning he was born between 9 November 1880 and 2 April 1881 and he is not the Second Lt on Dave’s list. However, errors regarding age and DoB are all too common in military records which in effect all three variations come from. One possible “error” is that he suddenly and “miraculously” grew a bit older when he attested.
