I have an interest in your Frederick Brewer's father Thomas. James Brewer was my great grandfather. He was born around1808 in Exminster. I have a possible baptism on 25/6/1809 at Exminster - parents Thomas and Mary. Perhaps James and Frederick are related. Frederick Brewer is in the 1851 census living in Alphington with his wife Ann aged 33 ( I have a few more details) I have also noted abaptism of Thomas Brewer on 30/2/1780 at Alphington.
