My great grandfather was illegitimate. I have been trying to narrow down a father via DNA. I am certain of his grandparents as I have many DNA matches that go back to them. I am sure of this as its the only branch of my family that hails from Staffordshire. But they had 6 sons. How do I narrow this down , or is that as far as I can go? Any help would be much appreciated.
My Great Grandfather- William Thomas Spicer B 1875 Lower Penn, Staffs
