are you sure you have the correct John Cubbon in St Marks - strange that not in Fam hist transcription - there was a John Cubbon buried there in Jan 1793
I havn't photos of the two Crellin wills - summaries taken from my reading of the microfilm are on my site but I didn't note any nickname against Alice Cubbon als Crellin nor her husband - I can be careless once but twice seems very bad
land records - many are summarised on my CD - but lib assed etc have been filmed my mormons - the deeds are paper only at museum 20,000 deeds pre 1847 I've summarised some 6000+ on my cd
