Another name for Richard was PEDRICK.
The information on Richard Pedderick and Sarah Vinney came from a publicly posted family tree. I have been unable to find any supporting documentation that these are the parents of William and Arthur Petherick/Pedderick. This relationship is, therefore, only speculative and further research is needed.
Richard married Sarah VINNEY about 1774 in Devon County, England. (Sarah VINNEY was born about 1761 in prob. Devon County, England and died in prob. Devon County, England.)
