I am descended from some Hertfordshire Plumes in Great Amwell and Broxbourne/Wormley. There is a bit of a Plume hotspot in Sible Hedingham, not far from Colchester, I assume that somehowI connect there.
one of my very distant cousins has made the site below. www.users.surfaid.org/~jackson01/plumesit contains a lot of Plumes Post 1730.
As far as the origins of the Plumes in varius threads here there are many Plumes on the IGI dating back to 1500's so they have been in England a long time, The ones I have been interested seem to originate in Essex, which is a short hop for the Norman French of 1066.
