We construct new families of $\text{AdS}_2 \times S^2 \times S^2$ solutionswith 4 supercharges in Type II supergravities. We show that subclasses of thesesolutions can be interpreted in terms of defect branes embedded in 4d$\mathcal{N} = 4 $ SYM, or orbifolds thereof. This is explicitly realised byshowing that the solutions asymptote locally to $\text{AdS}_5 \timesS^5/\mathbb{Z}_n$, in Type IIB, or its T-dual background, in Type IIA. Thelatter is a Gaiotto-Maldacena geometry realised on an intersection of D4 andNS5 branes. We extend the Type IIA solutions to include D6 branes, andinterpret them as describing backreacted baryon vertices within 4d $\mathcal{N}= 2$ CFTs living in D4-NS5-D6 intersections. We propose explicit quiver quantummechanics in which the defect branes play the role of colour branes, with theD4 branes of the D4-NS5-D6 intersection becoming flavour branes. These quiversare used to compute the degeneracies of the ground states of the dual superconformal quantum mechanics, that are shown to agree with the holographicexpressions.
