  We study the loci of the Brocard points over two selected families of
triangles: (i) 2 vertices fixed on a circumference and a third one which sweeps
it, (ii) Poncelet 3-periodics in the homothetic ellipse pair. Loci obtained
include circles, ellipses, and teardrop-like curves. We derive expressions for
both curves and their areas. We also study the locus of the vertices of Brocard
triangles over the homothetic and Brocard-poristic Poncelet families.
