Per my previous posting, the book you reference has a transcription error.
I have personally seen the hand written records of Bethlehem Baptist Church.They specifically state "David Strait and wife Charlotte and sister Dorcus Strait"There is also mention of William and Mary Strait.
The following deed and death record of Winfred Strait Witherspoon, daughter of William Strait, also states Mary - Winfred was born 1785, the deed is 1821.Both records state Mary or M.
In all the records available in Allen County KY, there is only one 1801 reference to Dorcas as wife of William, - obviously an error when all other records point to Mary.You should always verify information from multiple sources, and when someone with information from primary sources, not secondary source published books that could and often do have errors, points out the errors, it might be worth taking a second look.
