Hi DutchMissMarple
The quick response earns a quick one from me, as I started to list the details as soon as I posted my message and have had today free to work on it. As a result, I can give you the following which may or may not be helpful. It is a lengthy list, but might give some clues. I can certainly help with a few of the details from James senior onwards, but not from the birthday book - just based on memory and a bit of amateur-ish research. Genealogy was not considered important before most of the people who could have helped had died! I have left the data in a form that can readily be put into a table for ease of sorting. The following list shows names as shown, relationship to James junior and birth date and year if shown. Be warned, they may not be 100% reliable, as I have found with some other entries in old family records. I have also added a few notes that may help.
