Flamborough was a small place and the majority of the inhabitants worked either on the sea as mariners or fishermen or on the land.
Halifax was right in the middle of the weaving country, many people being involved in the wool trade in one way or another.
So the family story about Flamborough, is it possible to work out how old that story is?
I know from a story in my family that 'they came from a certain village' I have been able to prove with what I have found out that they lived in that village for less than 10 years.
Maybe a branch did move to Flamborough, this is why the pre 1724 PRs for Flamborough are important. With them you will be able to see wether Flamborough is a red herring or not.
