Stephen Carroll who went to Ark with the Old Settler Cherokee group was married to Nancy Ward. You will notice repeatedly that cherokee ancestors used step dads names or maiden or even other mates names. SO Susie Carroll could be Susan Ward, dtr of Nancy Ward who was married to Stephen.
Haven't followed all the posts but thought that tidbit might help someone.
ALso make sure you are untangling the Hugh Carroll's from the Drewery Carroll lineage over in Scott County, TN. I have never been able to connect Drewery with STephen. These lines are heavily intermarried Cherokee tho. My GGG grandmother married once into this lineage.
