Definitely possible. Go to one of the ancestry sites and see if you can trace your ancestors back to Isiah. Even if you're not related you'll find out that you have some fascinating relatives you knew nothing about. Have fun.
My suggestion is to isit or conact National archives. Many volunteers to help you trace your ancestry and it costs nothing . I visited the museum a couple months ago. Isaiah came from Rhode Island.
Any Davenport could be kin to another. How would you expect anyone on this site to know that you are kin to someone.
