Wellington, Wyrwast, Cokam

In a MS. letter which I have relating to the siege of Taunton in the Civil war, is the following sentence, describing the movements of the royal army:— "The enemy on Friday last have quitted their garrisions in Wellington Wyrwast and Cokam houses; the two last they have burnt." I am not certain about the second name, which seems to be Wyrwast; and hsould be obliged by any information relative to these three houses.
