One of my family members has ancestry and I知 trying to figure out if my tree is accurate. She connected with a man who has studied his genealogy for a very long time with his family, she emailed him and he said yes this is our family. So they connected our tree together. Personally I want to find out for myself if it is true, because deep back to my 17th great grandfather is a man named sir Iain John Macfarlane, his mother is Barbara Stewart and his father is Andrew Macfarlane of Arrochar. I looked online to see if he did have a mother named Barbara stewart on familysearch, ancestry, geni, and they all say yes. Apparently her father is John Stewart 1st earl of Lennox and her mother is Margaret Montgomery, apparently that lineage leads to royalty such as king James vi. I was intrigued when I found that out but again it might be too good to be true. So I went back to what I do know, my 3rd great grandfather William Nelson Brattin. I知 trying to see if his lineage leads to my supposed 7th great grandmother Anne Macfarlane, where her lineage I think continues to the Macfarlanes.
I fear this might be impossible, I did see some sources saying Anne macfarlane is related to our brattin. But I知 stuck, anyone more experienced in genealogy I would love any advice or help. I know ancestry is not exactly factual, but I want to see if any of this is true.
