From the known and estimated birth dates of Verlinda's children, we estimate she married about 1790. From this, we guess her birth to be about 1770-1775. Thomas' second marriage is estimated to have taken place in the early 1770's. Since we have no date for the marriage, or for Verlinda's birth, it could be argued that she was the daughter of the second wife. I have placed her on my list by that estimated birth year, but nothing is cut in stone when there are so many unknown dates. I'm sorry I cannot be more exact.
