Hi Frances - thanks again for this. I'm not familiar with these records but they sound very useful. I've had a look for them on the FamilySearch Catalog and I can't see them - unless they're the records described as 'Manorial rolls of holders of property, 1507-1911' and 'Manorial rolls of holders of property, 1515-1911'. If so, I can access some of them at the London Family History Centre.
