All of these family trees going back many generations have a major problem.
They are all based on the assumption the father was accurately known in every case. This is highly unlikely and the larger the number of births involved the less likely it becomes.
But it's fun. Once you get back to a gateway American ancestor/ress, the rest of it has been professionally done, etc.
I Still Care: I mainly do direct ancestors but have had fun with some collaterals.
Was this King John the son of Henry I? I have two going back to him, can't get at my genealogy program on my pc which didn't crash but close to it.
I suppose we are all related; I've never found one American president unless Obama goes back to Wm. Conqueror on his mother's side or this King John.
I found a lost line actually two or more lines on my mother's side. They manufactured guns in Kansas City. I look for everybody no matter how insignificant their lives may have seemed to others. And am major stuck on three brick walls I'd like to break through.
I've loved meeting like 3rd cousins I didn't know I had and corresponding with them. We had a published genealogy on my father's side which gave me a head start. But my mother worked on it a few years before she died. The clues she left were priceless, and with the internet, I made connections that I might never have made. My gr grandfather was a twin, and my mother lost the other one in Nebraska. I met up with a descendant of the lost twin, and I had the "rosetta stone" or where to look going further back, I knew his parents and a sibling had died from small pox. Later the third cousin I met confirmed it when he found an obscure diary left by a fellow in PA. He had traced his to IL then was stuck until I told him what county they were from in PA and how the census made it so hard to find the surviving orphaned children. It all came together at last.
I was just going to post something similar.
Genealogy is interesting and fun but I think “family secrets” mean most of us don’t really know what we think we know.
