Just a quick thank you to those who helped in connection with the above, and the continuing whittling away at the problem. Chris Phillips notes the references in the PRO to Sir Henry - in fact he appears all over the place (Yorkshire, Kent, London, Herefordshire, South Wales, Durham and Northumberland) - often identifiable by the presence of Gully Merrick (various spellings) until this chap got the chop along with the Earl of Essex, and afterwards by the presence of servants such as John Starkey - an interesting survivor, but more vulnerable once James I came to power.
