It appears that John Wood senior died between 1829 and 1832. At a recommittal ceremony at Easy Hall in 2009, John Wood, attorney to William Alleyne Culpeper senior, was shown as dying 28/11/1829 aged 86.
The 1832 Barbados Slave Register for BA8472 refers to John Wood senior as having died; it's assumed that this was the same person.
http://keltruthblog.com/blog/?p=462 [accessed 20/08/2018]. There were two awards to men called John Wood in Barbados: John Wood, awardee, Barbados 3937 [22 Enslaved] and John Wood, awardee, Barbados 4168 [22 Enslaved].
The dates listed below have different categories as denoted by the letters in the brackets following each date. Here is a key to explain those letter codes:
