Well, I said I would be back.
Retlaw has kindly confirmed to me that he has records of two of my relatives - Charles Swann (Army) and Herbert Swann (Navy) having served during the First World War.
I was slightly puzzled as I was expecting a couple of other records to come up though.
Can anyone tell me what the 'rules' were re conscription - age ranges, marital status, reserved occupations, other reasons for not being eligible ...... etc?
And Retlaw has also let me know that both Herbert and Charles' names appeared on the Roll of Honour in the Whalley Road Primitive Methodist Chapel, which made me feel very very proud of my relationship to them.
