Hi Richard, I wait to see what other listers say but I think you might struggle with a Militia list for 1618. So I'm forced to suggest the usual approaches (not in any particular order) 1) check the List and Index Society Volumes to see if they have turned up something suitable 2) try checking other records from the parish chest deposited at WRO and local wills 3) Try E179 Tax Returns to see if you can trace Captain John Selfe (National Archive) 4) Try Bernau index (at Society of Geneologists) - I've had a fair amount of luck with this particularly depositions held at TNA which are not indexed at the deponent level in A2A 5) Try Wiltshire Record Society volumes 6) Call Wiltshire Record Office ! Best Regards Richard Heaton
