Hi,
just to say I've searched the old Phillimores Marriages records hoping to find their Marriage within the Michel Dean or Huntley Parish sections, but sadly no luck, sorry.

However thought it might be worth posting links to these useful free websites for the various Phillimore's Books which are still available.

Volume 9, includes Michel Dean (1680-1812)

Also some other Gloucestershire Volumes can be read on this great site (search the site for Glos or Dean etc, lots of other good stuff too); sadly only a few Dean Parishes are included within the available Phillimores, eg Michel Dean and Huntley.
Volume 16, includes Huntley (1583-1837) starting here

Also available are Severnside parishes such as Alvington & Maisemore, see this "index" page to the complete original series of books.

As far as I'm aware only SOME of the listed Volumes are available f-o-c online, altho as I've lost all my reference data & transcripts I may be wrong. Those available definitely include vols 4,6,8,15 and 16 on the above "archive.org" site, also 9 as first link, and Vol 14 (Maisemore etc) http://parishroots.co.uk/tag/maisemore-marriages/

Alternatively they can be bought in cd format altho prices vary enormously !
