I have never seen the family tree you mention here but agree that there is alot of misinformation out there. I think that DNA will eventually solve this mystery about which Morgan family group Daniel belongs to. My research indicates that Willoughby died without issue making a y-dna test impossible. I have however been in touch with a direct descendant of Daniel's daughter and Presley Neville. Family Tree DNA's new Family Finder DNA test could possible make the connection. I have had a Family Finder DNA match in the last week with a "Heard" connection. Daniel's other daughter married a Heard as you will remember. I will make contact with this gentleman to see if his Heard line is a direct line to Daniel's daughter and post my findings here.
