Hi all and many thanks for your input
The neighbor asked friends including 2 attorneys who echoed and affirmed my position.
All discussion was cordial. After all that I offered to cut up all small stuff, removed some hangers from an adjacent Holly tree and placed debris at the adjacent curb.
Lady neighbor was ecstatic and was very quick to accept responsibility for the (much larger) remaining debris.
A local 'wood booger' did come by and took some the stuff to burn.
Too, we have some 'down the road'plans for developing our 2 acre parcel, so this was a good outcome that can't hurt neighborly relations.
Many thanks
