Elizabeth Beekman

"John Beekman of New York City and Some of His Descendants" Mrs. L. Sprague DeCamp NYGBR v81 p134 "Theophilus married Elizabeth Mathews, a daughter of Vincent Mathews "of Cornwal Precinct, Orange County, Esq." In the latter's will, dated March 12, 1783 and proved June 21, 1784, he mentioned his first wife Catalina Abeel and his second wife Elizabeth, both deceased, and children in this order: Fletcher Mathews, James Mathews, Bridget Jones, David Mathews, and Elizabeth Beekman. From the text it is inferred that his "late wife Elizabeth" is mother only of daughter Elizabeth, wife of Theophilus Beekman. This will, which was filed in Albany as well as New York, named Theophilus executor."

"General Daniel Bissell : his ancestors and descendants and the Hoyt, Strong, and other families" Edith Newbold Jessop New York, NY, 1927. p100: "By his second wife, Elizabeth Wileman: Elizabeth Mathews. Married Theophilus Beekman."
