1. Bury was definately Bury in Greater Manchester not Suffolk. He may have had a family connection to the Regiment that he joined
2. Because that was what it was known as in 1903.
3. Yes, it was his local regiment, being born and bred in Manchester
4. Because he did 5 years with the colours and 7 years with the reserve. That 7 years didnt count towards his pension
5. The Militia was not the regular army, it was not the volunteer army. It was a force paid an annual bounty and requiring minimal yearly training. Google the militia and you will get the best answer.
