Yes, I have subsequently found other Ralphs in my tree whose baptismal names are Randolphus.
I did find Margrt as you quote, but this implies age of 12-13 as Randoll’s age at her birth, possible but unlikely, and would have been indicated as a ‘base birth’. Alternative explanation is that Margt’s father was more likely Morgan-30468”s father or uncle.
If there is but one Randall, one must acknowledge one child in 1592, and the next recorded one about 20 years later. Suggests either two persons, a loss of many records, a prolonged period as a widower, or a prolonged period of infertility.
So much speculation!
