I'm not sure what information you are looking for.
David Bonner and Elizabeth Mckillop had a son, James, baptised Coldingham, 5 August 1770.
Snippets with reference to 'Bonnar' here but not sure if this would be your James.

There are others that I haven't accessed. I put 'books on bees Bonnar in the google search and several appeared.
However this may not be your James!
