Re: Martha Lumb - Yorkshire, 1788
Yes, I found it a few days ago.I entered 'Lumb' into the Google search engine and that was many of the Lumb-associated items that came up.
My folk are from an area about nine or ten miles WSW of Leeds, not too close to your folk, but we shall see if owt turns up.
(I assume you know a bit of Yorkshire dialect.'Owt' = anything)
