I have a family on my tree (Qualls Family Tree- Qualls-929) where the parents listed on my tree, John Nicholson (nicholson-9482) and Sara Howe (Howe-12425) are the wrong parents to the William C. Nicholson (Nicholson-9483).
The correct parents are Jackson Nicholson (Nicholson-3770) and Sara Jane Holt (DOB 26 Dec 1842). I can not find a record for Sara in Wikitree. I can find her in other sites such as Ancestry.com and Geni.com She married Jackson Nicholson (Nicholson-3770) in 1870's.
There is a documentation on Ancestry.com referencing that Jackson and Sara had only one child and his name was William Christopher Nicholson. I tried to find it, but could not.
