Hi Sarah,
Welcome to MLU from me too ... another woman in here! I'm sure you'll get some great information and/or leads regards your Granddad and/or his service, from MLU-ers. MLU is a wonderful place for finding out about our relatives WW2 service, or where to find out, and often even personal information about the relative when lucky! I hope you get really lucky here
