These two images I found via Google search as well have been useful to map out where a DNA cousin eventually links back to a common ancestor (MRCA) when working with unknown lineages & NPE’s. By adding shared matches to a general DNA research tree in Ancestry, you eventually see a pattern. Work from the closest matches as possible & add their shared matches. The Leeds Method is also useful in creating clusters or groups of DNA matches that may link to a specific great grandparent.
