Most Tysons come from Cornelius Tyson, son of Theiss Peters, probably son of Peter Doors (he was definitely son of Peter, due to the patronymic Peters): Cornelius Teissen: Immigrated from Crefeld, Germany in 1703 and lived in Germantown until 1716 when he died. Married Margaret __(?)__ - had 6 children. Will written 6 Apr 1716 and proved 23 Jul 1716. Recorded in Philadelphia office for the Recording of Wills in Will Book D, p 54. One of Cornelius' sons, Peter, may have had no children (I haven't pursued that line). Most children were daughters, otherwise there was one son who was quite prolific: Matthias Tyson... Matthias (Imm) TYSON - 1758 Will Source: Cornelius TYSON Descendents, by G. A. Kerr-Tyson "I nominate my two sons, Cornelius and John TYSON to be my executors. To Barbara Sellen TYSON, my beloved wife, all my household goods, one cow, the sum of Two Hundred Pounds, should any part remain after her decease and the funeral expenses are paid, said sum shall be divided into eight equal parts to be paid when they are twenty one or married which may happen first. The remaining estate equally among my eight children. Cornelius, one eighth; Henry TYSON, one eighth in trust [Henry was blind], to be paid to the granddaughters, Sibilla and Barbara. The third eighth to Margaret and her four sons she had by Jacobus PENNEBECKER, viz: Matthias, Henry, Barbara, and Jacobus. The fourth eighth to be divided among children of Peter, viz: Mary, Barbara, Cornelius, Catharine, and Joseph. The remaining four eighths to sons, William, John, Benjamin, and Joseph. Ratifying and confirming this writing, contained in two pages and this part of the third page of this one sheet of midling, to be my last will and testament." Witnesses: John BOCKIUS Joseph ASHMEAD Thomas ROSE I looked in the book for Phebe, but couldn't find her. Once you make your exact Tyson link, I can scan the info from the book. I am descended from Cornelius through two lines. Michel Michel
