OK, first, it the THRU Lines not TRUE lines. The connections may be real or not. There needs to be an investigation as to whether the descendants of a known forbearer are documented with citations, not just a guess by a potential cousin.
I have followed a number of suggestions on how to break out the various lineages in Excel and to be able to then see a picture of what is known and what needs to be proven.
Today, I started with one of my maternal lines — lineage for my grandmother’s uncle’s descendants. I had previously tried to contact one of my distant cousins and there was no reply (unfortunately this is the norm for DNA inquiries). Well, today I sent a note to what appears to be her sister. Within an hour, I got a reply with information that meshed with my citation documentation. This may have been a third cousin, twice removed, but I chalk it up as a success! Just the incentive needed to keep working the project.
