Bob - who are you?

"Herb Robert is held in great estimation by farmers who use it in diseases
of their cattle. .........

.....is commended not only against the stone but to stay
blood........

.....is effectual in old ulcers in the privy parts,
or elsewhere..."

(Culpeper)

I love the names of wild flowers. But who was Robert?
