Hand rolled beaker & a jug, stamped Jess

Two porcelain pieces by the same potter, one hand rolled, both with applied beads.
The impressed mark is very small, but with such a distinctive style I am hoping it is an obvious one for someone.
Very recent in age, I believe.
The potter is possibly from York.
Any help appreciated.

And the beaker...

Thanks very much denby that gives me something more to go on, greatly appreciated.
All I was seeing was an O, which is not there at all. My eyes are dreadful

Possibly Jessica Joslin, though yet to confirm.
Whether it's one of her own, or a "paint your own piece" from her pottery workshop, I do not yet know. I'll update this if and when I get to the bottom of it
Thanks again Denby
