Figuring out whether and how two people not on the same screen are related is, uh, difficult at best in that website. :’)
I don't think it can be done from the website (you can sketch out a a chart and I used to know how to figure it out the old way), so I carefully picked through that pedigree, entered all the relevant names in my genealogy program which has a relationship calculator, and if I entered it all correctly and if the data is correct, came up with Sarah is my 9th cousin once removed two different ways and 10th cousin once removed a third way, not real close.
Basically you have to find a common direct ancestor you share with Sarah or any of the others listed there from their pedigrees, work that line back down to the person of interest, work your line back down from the same common ancestor to you, then you can figure it out or have somebody do it for you. There are various (confusing to me) explanations of how to do it on the web, don't have any links for those.
