I have that entire Meredith family documented fully back to the mid-1700's including the McVann connection from Cloonacool, Sligo, Ireland. Tubbercurry is nearby and is the local registration district for BDM records.
I am very interested in learning more about your McVann family to include in the Meredith family history.
I recently finished a book regarding the Meredith family from Sligo that you may all be interested in.
From The West - The Merediths of County Sligo, Ireland.
Let me know if you are still ative here.
