Hi Brenda It's me again, Maria. If you can find it, there is a book called "Kissin' Kin"It talks about the Boon Family,Alexander Family is mintioned as well. I have been researching the Alexanders for about 5 yrs now and haven't been able to find out more about Mary "Polly" or Elisha. Some believe that Elisha might be one of the sons of Joab or Jacob Alexander, but no proof yet. Hope the book is of help to you.
