My search for more information about Nicholas and Susanna led me to a marriage record for Nicholas Hyne and Susanna Yeolland from Plymouth, St. Andrews, Devon. According to the record, Nicholas was from Tavistoke and was a serge weaver. Unfortunately, this Nicholas seems to have had the wrong occupation. Additionally, there is a Nicholas and Susanna who baptized nine children in Plymouth, St. Andrew, Devon.
The Nicholas and Susanna who married in Plymouth, and baptized children in Plymouth are therefore unlikely to be the Nicholas and Susanna that I am looking for: those who baptized their four children in Blackawton. So I went back to searching.
Recently I’ve discovered a marriage record for a Nicholas Hayne of Blackawton who married a Susanna Colston of Ashprington, in that parish, on April 5, 1770.
Looking closely at Nicholas’ signature, it looks to me like “Hyne”. I definitely do not see an “A”:
Given the apparent signature, and the connection to Blackawton, I currently believe that this is most likely the marriage of Nicholas and Susanna who baptized in Blackawton, or at least the best candidate I’ve yet found.
