I've got a lot of SILVERs in my tree, some are cousins, some are related by marriage only. After I saw your message, I looked at the Birth Index to find the parents of Mary Davis Silver, and found I have them in my tree. Her parents were WILLIAM LEE SILVER, b. 1904 Warren Co.,NC/d. Sept. 26, 1980 Louisburg, Franklin Co.,NC, and ANNIE RICHARDSON, b. June 21, 1908 Warren Co., d. June 24, 1990 Louisburg; they're both buried at the Tillman P. Lynch Cemetery in Halifax Co.
WILLIAM LEE SILVER was the son of JONES LEE ROBERT SILVER (1871-1947) & LOUISA L. RICHARDSON (1879-1949); JONES was the son of WILLIAM HENRY SILVER (1846-1929) & NANCY ANN RICHARDSON (1849-1926); WILLIAM H. was the son of JONES LEE (b.1825) & MARTHA SILVER, b. 1828. JONES LEE was white, he & MARTHA were not married, but they had several children together. MARTHA's mother was SUSAN SILVER (b. 1780/d.shortly after 1870) and an Unknown father; SUSAN was not married and had several children. She was the dau/of EDWARD SILVER & MILLY CHAVIS, b. 1749, from Granville Co.,NC.
These were all Free families who had never been slaves, so they are found in census, marriage and other records of the time.
