I am sure I will reply to you several times as I will fine bits and pieces in you message to comment about. Here is the first one.
I do not have documentation but I have been told that Gov. Robert Daniell had an affair with Martha Wainwright and had John Daniell then he requested a divorce. That is why the b/d for John is before the date you found in regards to his first wife.
I do not know what else to say at the moment. I will reply again soon with our lineage.
