We give conjectures on the form of families of integer sequences whose Hankel transforms are, respectively, $(α, β)$ Somos $4$ sequences, $(α, 0, γ)$ Somos $6$ sequences, and $(α, β, γ, δ)$ Somos $8$ sequences, for particular values of $α$, $β$, $γ$, $δ$ which we describe. The sequences involved can be described in terms of the application of certain stretched Riordan arrays to the Catalan numbers, accompanied by a (sequence) Hankel transform. The combination of Riordan array and the Catalan numbers results from the study of certain generalized Jacobi continued fractions, based on the Counting Automata Methodology.
