Tom, I have noted that you have some very interesting information. Our research indicates that the St. Helen's Barracks were built on part of the Caldwell Hall Estate which was leased to the Government by a John Rivers in about 1804. The Estate lands extended over more than one Ipswich Parish. We are particularly interested in finding out how many acres of the Rivers property was in the parish of St. Helens. One of our ancestors John Hill was employed as a miller at the St. Helens Barrack's which was a temporary facility established during the conflict with Napoleon.
