Just a quick note re your 'wrench' ie cousin Samuel . . .
As you have alluded to yourself I would put good money on this being a brother, an earlier Samuel who died in infancy and the name was repurposed, as you theorized yourself, to be given to your direct ancestor to whom I shall refer to as Samuel Jr from now on to avoid confusion . . .
So, now we have . . .
Samuel Sr
Samuel Infant
Samuel Jr
(Does that make sense 😁😁😁)
Repurposing Christian names was common, in my experience, especially with a Christian name that meant a lot to the family . . .
I hope that unwrenches your wrench 😂
