The 1910 census lists them in Granville:

He is listed as in his second marriage - and he and Mary as married 5 years

I do not see him on the slave birth lists for the Waverly Plantation (Mecklenburg VA).

In 1900 I see a Mary Herndon:

Name: Mary Herndon
Home in 1900: Durham, Durham, North Carolina
Age: 18
Estimated Birth Year: abt 1882
BirthPlace: North Carolina
Relationship to head-of-house: Servant

Don't see a Robert around the correct age in 1900 - born in VA.

In 1880:
Name: Robt. Baskerville
Home in 1880: South Hill, Mecklenburg, Virginia
Age: 25
Estimated Birth Year: abt 1855
BirthPlace: Virginia
Relation to head-of-household: Something other than a direct relationship
Father's birthplace: VA
Mother's birthplace: VA
Neighbors: View others on page
Occupation: Farm Laborer
Marital status: Single
Race: Black
Gender: Male

I do not see him in 1870.

Am wondering if he used another first name?

Do you have his marriage reocrd to Mary?
