Those of you who have been following the Corder Family DNA project will know that we had a genetic mismatch between two sons of Susannah [maiden name unknown] Corder, wife of Edward Corder II. Eldest son Benjamin Corder's Y-DNA signature does not match the Y-DNA signatures of younger sons Elijah Corder Sr. and Stephen Corder. This has lead us to conclude that Susannah already had one or more children when she married Edward Corder II sometime in the 1760's. It is possible that Susannah had a prior marriage, as she apparently also had one or more daughters believed to be older than Benjamin.
On January 19, 1797 Elizabeth Corder (daughter of Susannah, although she may or may not have been the biological child of Edward) married Thomas Cassidy in Burke's Garden, Tazewell County, VA (formerly Montgomery County, VA). Thomas and Elizabeth Corder Cassidy had six children before she died in about 1815. They were: Hiram b. ca 1799, Benjamin b. October 18, 1800; Elizabeth b. ca 1806; Thomas b. ca 1812; Harve b. ca 1814; and Margaret b. ca 1815.
It looks like Elizabeth named one child for her brother Benjamin. She named a younger son Harve (Harvey).
Benjamin's family line uses the name Harvey frequently through the subsequent generations. Notice that Elizabeth does not name any of her children Edward, nor does she name any of her sons after her younger brothers. From what I've seen, the lines of Edward's biological sons do not use the names Benjamin or Harvey (although they do use Stephen, Edward, John [a brother to Edward II], Elijah, and Elinor [possibly the name of Edward II's mother] frequently).
Based on these naming patterns, I wonder if it makes sense to theorize that Elizabeth and Benjamin were full siblings through their mother Mary Susannah's (or Susannah Mary) first marriage, and that either Susannah's maiden name was Harvey (although if so, you would think that the name would have been passed through the younger Corder lines as well), or more likely, their biological father was named Harvey (first or last name)?
