Thank you for asking but her testing would not be useful to resolving my situation.
However, I encourage all of my Cousins to test regardless. The more Seale Cousins we have tested, the more we will know collectively about the Seale descendants.
If she is willing to test, I encourage you to get her tested.
You just never know if it might be able to help someone else solve their brickwall!
Besides, testing the oldest generations first is one of the best things you can do because their DNA is more useful in solving brickwalls that are further back in the tree.
