I'm working with my wife (Gweldia Akins Gannon ) on her family tree so I'll respond. She is also a direct descendent of Wm Aiken 1 And Wm Aiken 11 but connecting all the dots has not been easy. We can document back to her grgr grandfather, Martin Aiken. His father is supposed to be Wm Aiken 111 but he is a black hole- almost nothing on him. We have used the work, Descendents of William Aiken and Allied Families, compiled by Pearle Tulpin Forrester and Julie E. Tulpin. It's widely circulated so maybe you have it. I would be interested in seeing the family tree constructed by your great uncle Joseph Aiken. Perhaps there may be clues to help us fill un our gaps. If it's more convenient, you can email me at email@example.com. Keep in touch.
