I am in genealogy group of distant cousins all descendants from Maynard & Reeves families of Kent. You might be interested in joining our discussion group.
You have the marriage data for John & Phildelphia Lockyer from another messager, so I will restrict myself to what is probably "your" John Maynard b. abt 1782, ent (I will have to look up futher where) son of James Maynard b 2 Jan 1760 West Malling, Kent and his 2nd wife Sarah Cramp b. abt 1803 Bodiam, E.Sussex.
Best regards, Jeremy.
