White was the 14th most common black name in the United States in absolute numbers. My mother's maiden name was !!!!!!! by the way. In percentage terms, the surname with the highest percentage of blacks using that name had a percentage of 89.87% of the total using that surname.
I think revealing your mother's maiden name is dangerous - people can apply for credit cards etc.
All my real names are very common - in fact in the bangkok airport recently I was paged and met a strange man looking for another one with my name.
