  We give conjectures on the form of families of integer sequences whose Hankel
transforms are, respectively, $(\alpha, \beta)$ Somos $4$ sequences, $(\alpha,
0, \gamma)$ Somos $6$ sequences, and $(\alpha, \beta, \gamma, \delta)$ Somos
$8$ sequences, for particular values of $\alpha$, $\beta$, $\gamma$, $\delta$
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.
