my great grandfather was in the 4th dragoon guards 1871-1883. His regiment were at aldershot barracks 1880-1882. He married at Preston parish church (by banns) a week after he left the army. This makes me presume that from 1882-1883 the regiment were at preston barracks. Can you confirm this and,if possible, confirm if the regiment were also stationed at Preston at any other time during his service period?
