Hi Helen: I have not read Pippingers' book on this John Alexander. I am researching the Mecklenburg Va. line,and saw some letters that alluded to a connection through marriage to the Watts family in the Stafford area, I believe. the Virginia Heraldica stated: Alexander: Stafford County; according to the family tradition,which has not been proven by documentary evidence, John Alexander the first of the name in Virginia,was the fourth son of William Alexander the poet, and first Earl of Stirling, born 1580, died 1640 and married Janet Erskine, daughter of Sir William Erskine. John Alexander obtained a grant of 1,500 acres in Northampton County in 1659. In 1664 as John Alexander Sr.;he patented land in Westmoreland County. He died in 1677 and had issue, John Robert and Phillip, who may have been the John and Phillip Alexander whom Alexandria Va. is named for.
