I read with interest about your Beds/Bucks Daniell families.I have a possible addition and query.My branch of the family I have traced to a John Daniell to Long Marston, nr Tring, Herts (just on Herts/Bucks border).He died in 1837 aged 70 - therefore born 1766/7.Unfortunately he moved into the area - but I have no idea where from.One obvious option is from Bucks and I note there were two 'John Daniell'sborn in 1767 in Bucks 1) John, son of Thomas and Frances Daniel in W. Bletchley (Thomas was a Glazier) 2) John son of Joseph and Anne Daniel of Bletchley (Joseph was a labourer).I favour Thomas and Frances as parents as John of my line had an excellent signature showing that he had been shooled.(He also became parish clerk of Long Marston).On John's marraige certificate his name has the double 'll' - by histhe name had changed to 'Daniels'.Only my branch of the family kept the double 'll' form of the name.
On the 1841 Census some grand-daughters came from Worminghall, Bucks, but I am not sure if this is a Daniell connection.
Any further references / help greatly received! (I have a number of references to Daniell familes in the Bletchley area and Fenny Stratford area.
Also - there is a Daniell clan in Berkhampstead, Herts, with a full crest and lineage in Debretts!
