Continuing to be a bit confused, there is an interesting biographical sketch of Benjamin Duvall, "The Glass Industry in Brooke County" on the Brooke High School, Wellsburg, WV website ( http://bhs.broo.k12.wv.us/brk-hist/gibc.htmhttp://bhs.broo.k12.wv.us/brk-hist/gibc.htm ), but,
from: Newman, Harry Wright, Mareen Duvall of Middle Plantation, (Washington, DC: H W Newman, 1952), Family History Library, SLC, JSMB, 929.273 D956n, also film #896885 item 1
On July 27, 1791, he (Lt Jacob Duvall] secured license in Prince Georges County to marry Jemina Anne Taylor, who was his brother's step-daughter, being the daughter of Mrs. Marsh Mareen Duvall by a previous marriage, or the daughter of Joseph and Susannah (Watkins) Taylor [Susannah Watkins being the second wife of the Capt, and he, her third husband -- note by Bill].
Benjamin Duvall, son of Benjamin and Susannah (Tyler) Duvall, was born November 5, 1746, Queen Anne's Parish, Prince Georges County. He married about 1772 Jemina, the youngest child of Richard and Jemina (Godman) Taylor and the granddaughter of Richard and Anne (Tatloe) Taylor, all early parishioners of All Hallow's. She was born and raised at "Middle Plantation", which was leased by her father from Madame Anne Whey whose name is carried on the rent rolls with that of Richard Taylor.
So, Happy Mother's Day! There seem to be, by Harry Newman's own hand, two Jemina Taylors. Thanks to all who have helped to identify this fact and elucidate the marriages involved.
