I found this site by enormous luck.
www.sponend.org.uk/sebpt/index.htm

Black Swan terrace built in 1450 is under reconstruction/preservation. The census is published of the people living in the terrace. Worth everyone checking. I found My Evitts family and I had hit a brick wall. Great luck as I live in Lancashire and had never even heard of Spon End.
if anyone has any connection I would love to hear
