Zara Zonell Mercer - I would like to help but not sure I can since I probably cannot see your tree and don't know the path from him to you. He appears to be Nancy Robert's father.
I'll tell you what - I will temporarily join your tree and help you straighten this out. I will need to work through each generation to see if there is an actual problem. Sometimes Geni's algorithm calculates a more convoluted path because that's what was "cached" (calculated previously and hung around). If so, I can "force" it to calculate the straight forward path.
Send me a family group invite and let's discuss this in Geni email since the details of your private tree should stay private.
