WikiTree,FamilySearch,and the book 'The Descendants of Matthew "The Rebel" Rhea of Scotland and Ireland' give the parents as Archibald RheaArchibald Baxter Rhea and Ann Humphryes as the biological parents.I've tried to disconnect the incorrect parents(actually uncle and aunt),but the best I could do to reclassify the incorrect parents as foster/adoptive.Is there a better workaround to address this?
