Thomas Alfred Derrick - WW1

[Lisajb]

Given that a large number of records were destroyed, I realise this may be an impossible task, but would appreciate any input.

Ancestry have sent me a hint for a Thomas Alfred Derrick, from the service medal and award rolls. He’s a private in the Army Service Corps, regimental number S/389001.

My grandmothers first husband was a Thomas A Derrick, so I am wondering if it’s the same chap. I’ve asked my mother - her daughter, and she doesn’t know. I have a baptism for him, Thomas Alfred Derrick.

Could anyone find out anything more about the chap in the Army Service Corps?

Thanks
Lisa
