John Caswell m Jone Pontinge Mar 25 1658
As per his fathers will, John is a Captain. (Of what I am not sure)
There is an entry in the Essex Historical Collection Vol 2p44 where this John is mentioned as son of Robert the elder of Yatesbury, dated 8 Dec 1610 & 6 June 1611. The article is of the will of Thomas Arnold of Yeatesbury and it proves the line of the Popes of Salem USA, as well as their connection to the Caswells.
In the Bremhill burial records, there is a John Coxwell buried 9 De c 1661.
There are no other likely candidates than our John Caswell for this record.
