To me it looks like ( from the Find a Grave Source on James profile) you have connected the son of James Dunivan and Sarah Carney... to his mother as her husband.
To remove Sarah as his wife...Go into edit mode on his profile, on the right hand side of the page find the section for spouse, click on add/remove spouse (just under names of spouses). You need the Wikitree I.D. for Sarah, enter it in the box for existing profiles and click Go.
He is also connected to the wrong parents if the Find a Grave source on his profile is correctly attached to him.
Please double check that all the information for James W. Dunivan is correct, then make your changes..
