Shenton - can anyone get any further?

Question

I'm struggling to tie up this Shenton with his alleged parents, There seem to be very few online resources,
I've found the wills of his supposed brothers, but there is no link between them there, except to each other:

https://www.wikitree.com/wiki/Space:Will_of_Robert_Shenton%2C_gent_of_Alkington%2C_Shropshire_1631

The only source I've found for the parent relationship is a single pedigree, which in itself isn't reliable:https://archive.org/details/bim_eighteenth-century_the-history-and-antiquit_nichols-john_1795_4/page/n643/mode/2up

Can anyone spot anything?

Comments

I'd like to make profiles for the brothers, but without any reliable sources for the parents, I'm reluctant,
