Hey Graham
I'm feeling quite overwhelmed & not sure where to start!!! I have received your pm, and will email to make sure we have that contact.
I am descended from Jonathan Nevill, brother of your John Benjamin Nevill as follows:
Jonathan Nevill (1774-1840) = Mary Ann Surflen (1789-1879)
George Nevill (1826-c1890) = Augusta Robinson Boddy (c1825 - 1872)
Annie Rose Nevill (1869-1940) = Richard Henry Cormack (1860-1946)
Arthur Richard Cormack (1893-1991) = Vera Newbon Shephard (1899-1969)
Bridget = Clem (my parents, still living)
Rosemary - me!
so Jonathan is my 3xgreat grandfather (cf his brother being your 5xgreat grandfather).
I have some independent info on their parents John Nevill (1717-1783) & Elizabeth Tring (not her maiden name) - apart from the research of ER Nevill - including their marriage licence & entries on the family from the moravian church records..... which I will be happy to share.
Edmund Robert Nevill or ERN (1862-1933), who did a great deal of Nevill research, was descended from an older brother of your William Nevill (1808-1874) as follows:
Jonathon Nevill (1806-1871) = Mary Berrey (? - 1884)
Edmund Berrey Nevill (1835-1875) = Mary Louise Linton (? - 1886)
Edmund Robert Nevill (1862 - 1933) = Lilian Ethel Bagley (1878-1969)
there is a lot of Nevill info - as researched by ERN - stored at the Society of Genealogists in London.... the publication I have (your target 1) is, I think, a reprint of the article originally published in The Genealogist (your target 2).
ERN also published on Nevills from other parts of the country, I think he divided them up into about 7 different groups - but I haven't copied it all
as we definitely fall in the Nevills of Suffolk group.
btw ERN & his father were ordained & both emigrated to New Zealand, and ERN's uncle was Samuel Tarrat Nevill, the first archbishop of NZ... accordingly if you google their names, you will find entries in the NZ National Dictionary of Biography & a database of NZ clergy
ok I will stop for now & send a few snippets by email .....
cheers
Rosemary
