The copy of the Shipley arms that we have has the following text:
"Thomas Raine of Sweet Shipley. Married ye daughter and Heir of Sir Simon Borard Lord of Clifton in Buckingham Shire, and had two other Lord Shipps, one in Bedford Shire and the other in Leicester Shire.
"He was by this macth Dns Raine de Clifton. Afterwards, severall of the Heirs of the said family of Raines married into the Worshipfull and Renowned viz.
( Maleverer of Yorkshire )
"Into ye family of ( Froike of ye West )
( Broughton of Cheshire )
( Booth of Chester )"
Mr Berrill, a Clifton Reynes expert who I consulted about this many years ago wrote that the armorial shield probably dates from the C17, and that the loss of the 's' from the surname is a worry. He wrote it could be that a Shipley Rayne obtained some information about the Buckinghamshire branch of the Reynes family and adjusted their arms accordingly. However he also wrote that the reference to Maleverer of York is most interesting, since it is not identified in the pedigree given by the Brudenall Family which was used by Lipscomb and other Buckinghamshire historians.
As you, say the existence of a Marwood in Kent that was connected with the Reynes of Clifton is interesting. Possibly the Marwood in Kent was named after Marwood in Teesdale, since Marwood is mentioned in the Durham copy of Symeon's Life of St Cuthbert written in 1050 AD, indicating that the name 'Marwood' existed in the north in 850 AD.
Have you considered the possibility of a connection with the Raymes of Aydon and Shortflatt in Northumbria?
