THE PARKERS - The family tree shows that the last of Mrs. Lincoln's Todd forbears to live in Europe married a Miss Parker. It is not known that this woman was of the Parker family that in later years was frequently intertwined with the Todds and the Porters in Pennsylvania and Kentucky. There is some likelihood that she was, since the two families were so closely associated and for so many years.

The Parker family must have been an excellent one. The family historians never fail to say so. At the same time, we do not find among them many men or women who were of great prominence. It was the cross between a Parker and a Porter, or a Parker and a Todd, or both, that seemed to produce a superior individual.

The Robert Parker who was Mrs. Lincoln's maternal grandfather was a man of wealth and social position, but the member of his family of whom we read most is his widow, Eliza Parker, and she was born a Porter the daughter of Andrew. The day after her marriage she and her husband left Pennsylvania and rode horseback through the wilderness to Kentucky. It was she, as the "Widow" Parker, who dominated her grandchildren and did so much to make them dissatisfied with their stepmother. The accounts agree that the " Widow " Parker lived in a fine house, had a high social position, and was esteemed a superior woman. However, it was her grandchildren who quarreled amongst themselves and engaged in family law- suits something new in the Todd-Porter-Parker family. pg. 36-37 MRS. ABRAHAM LINCOLN (1932) Author: W. A.
