William Surname Meaning and Family Facts
There is more to William family history than the origin of your surname:
A William Family History Thought:
'In all of us there is a hunger, marrow-deep, to know our heritage - to know who we are and where we have come from. Without this enriching knowledge, there is a hollow yearning. No matter what our attainments in life, there is still a vacuum. An emptiness. And the most disquieting loneliness.' --Alex Haley
