FamilySearch has a Fan Chart display mode you can use as a visual aid to see if your tree has source citations for each person. The tree is color-coded; the darker the color, the more source citations. This is a great tool to help you see which family lines need more research and sourcing.
FamilySearch family trees are community-owned trees that anyone can change. That makes one person’s research vulnerable to the human error of all others but can also make for a better-researched tree with multiple contributors.
A Well-Sourced Tree at FamilySearch
This is my husband’s family tree. The color key for this chart is:
- darkest orange color represents people with 10+ source citations
- medium orange represents 5-9 source citations
- light orange represents 1-4 source citations
- white represents 0 (zero) source citations

As you can see from his tree, most of his tree is well-sourced, with 10 or more sources per person. I guess you’d have to examine each source to argue the viability of the sources, but the general takeaway is people have taken time to source the names they add to this tree.
The one family line where he has fewer sources has known illegitimacy and I’m not sure if they’ve struggled to source the adoptive parents or are trying to source the birth parents.
A Poorly-Sourced Tree at FamilySearch
In comparison, here’s my tree at FamilySearch. Again, the color key for this chart is:
- darkest orange color represents people with 10+ source citations
- medium orange represents 5-9 source citations
- light orange represents 1-4 source citations
- white represents 0 (zero) source citations

You can see from the amount of white and
Part of the reason the right side of my tree is well-sourced is there are many, many descendants contributing to the genealogy research on this line. Their curiosity has bled over into some other lines going from right to left on my tree, but where they lose interest, I need to pick up the slack and start sourcing the genealogy.
It’s worth noting that just because a tree doesn’t have tons of sources, doesn’t mean the names are speculative. It might just mean
