Her name is spelled Raleigh, I am descended from their daughter Lois, and her husband Daniel Haynes. They are my 4th gr.grandparents.
Anyone descended from Andrew & Sarah (Raleigh) White is also a direct descendant of English Explorer, Sir Walter Raleigh.
My line to him goes :

1. Sarah Raleigh
2. Philip Raleigh + Joanna Sprague
3.Thomas Raleigh + unknown spouse
4. Philip Raleigh + Frances Grenville
5. Carew Raleigh + Phillippa Weston
6.Sir Walter Raleigh + (can't remember, I'm doing this off my head.).
You get the point. I remember reading about Sir Walter Raleigh in school, how strange to know I was reading about my ancestor.
