I have Heptinstall ancestors: Hannah HEPTINSTALL (1737-1825) of Hundel Hall, Pomfret and East Hardwick. Apparently a fairly well-connected Yorkshire family. Hannah was one of 5 sisters. She eloped with Thomas Brown (1737-1821) and they had 9 children.Related names are Kensington, Seaton, Rogers, Sewell, Fenning, Shipton and Sneade. I have not been able to locate much info on this branch past that in the book "Ayot Rectorya" by Carola Oman (1965).
