I agree this is a real mess. This is not my information, but I have to admit that I haven't really made an effort to upload much data into my own tree (I don't really have the time and to be honest I only set up this basic/free account in order to explore some material for a work-related research project), so I would not claim to be the person to manage or control any aspect of what is showing up on this website. I will go so far, however, to suggest that it looks to me as though someone is trying to merge two (at the very least) different, and as far as I know (unless DNA testing has indicated differently) unrelated Knox families into one, and in doing so has made quite a muddle of both. My ancestors were James and Elizabeth Craig Knox who settled in Chester Co., SC, and came from Ballymoney, County Antrim, Ireland. James Knox was born in Glasgow, Scotland (son of John and Agnes Johnstone Knox) and Elizabeth Craig Knox was born in Edinburgh, Scotland, daughter of John and Elizabeth Moir Craig. John Knox (father of James) was a burgess and guild brethren of Glasgow, while John Craig (father of Elizabeth) was a burgess and wright of Edinburgh. My research points in the direction of this Knox family being a cadet of the Knox of Silvieland family, while Agnes Johnstone's ancestors included a number of burgess and guild brethren of Glasgow. I have not been able to discover much about this Craig family, aside from the fact that John's father (James) was a farmer of Easthouses, Midlothian. Elizabeth Moir came from an Aberdeenshire family with links to the merchant/burgess class of that city.
Hope this helps.
