Sir Thomas Morgan, 1st Baronet of Llangattock - Robert, son of Thomas Morgan, father of Thomas ... where is he?

I get most of my info by Google, or some is found through sites like ancestry.com and of course, this one! I've found the same situation with a Great Great Grandfather Johnny Morgan. There are two profiles set up with two different pictures, and of course I have a family photo showing both men in the same picture because they are brothers! Some people enter bad info because they find a picture with no names, so they guess, mine have names. I have found info on this site, that was later removed, and then some that were completely changed.

As supplied in a PM:

==========================

That still leaves open the questions, though about at least:
Sir Thomas Morgan, 1st Baronet of Llangattock
Admiral Sir Henry Morgan, Privateer
Catherine Morgan (currently without any dates)
who don't fit with the 8 children noted above, yet all have attributions in their About that they are children of a Robert, (3rd) son of Sir Thomas Morgan of Llanryhmny
