I added a source for the birth of Elijah Boardman (1792-1873) and from it, I pulled his marriage date, his wife’s name, her birth date, and the name of her father. When I look at the source from Elijah’s record, it looks fine. (No screen shot due to limitations in bug reporting.)
However, when I look at the same source from his wife’s record, her father has been automatically added as Elijah’s father as well (the screenshot below is not the full person tab - the full tab shows Elijah at the top). If I go ahead and save this, RootsCity actually makes Martin Foote the father of both Mary Foote and Elijah Boardman.
