Hi Mary-Jane
Another dead end (sorry about the pun!). Our Luptons were in Great Crosby, Lancashire from about 1770. Before that, I think they were probably a bit further north in Lancs as there are lots of Luptons there. I regularly go to Crosby library which holds many of the local records and they do not seem to appear before then. Either that or they were "medium good" - not bad enough to be had up before the manorial court, but not good enough to be a court officer as they were in the early 1800s.
