The World Tree idea: how is having unknown names put into my tree a good thing?

Question

Answer 1

I don't think anyone likes unsourced & unknown profiles in the world tree. However, this is a collaborative effort & the tree is not yours & it is not mine, it is everyone's tree. Sometimes adding unknown profiles provide clues which lead to known profiles & brick walls broken.

If it turns out evidence is presented to show the links are inaccurate, they can be unlinked.

Answer 2

Can't see anything new here.  You connected Robert J Dixon to William Dixon (who already existed) and a long line of Dixons.

Elizabeth Murphrey came with William, as his mother.

If she's not your ancestor, perhaps he's the wrong William Dixon.
